This brings back memories, I used to use one of these when I worked at IBM East Fishkill, New York back in the EARLY 1980's One of these units was mounted on a 1 ton steel table that was bolted to the 10 inch thick concrete floor. We used it to weigh the amount of Nickel that was plated on a ceramic substrate that was 1 inch square by about 1/32 inch thick! Now having said this this, Interstate 84 was about 1/4 mile away maybe a little more from the building which was BLDG 330C phase, when a 18 wheeler rolled down the interstate, it would interfere with the readings on these type of scales, EVEN WHEN SOMEONE WALKED AROUND in back of me when doing the weigh process would send the optics into a "TIZZY" There was a small control that "LOCKED" the mechanism when not in use and when and if you ever had to move the device you had to take out the pan and suspender cage it was hung from to prevent internal damage!! John Bellas KC2UVN Thanks for the memories Ron!! Had to share my story!!
There are shipping hold downs attached to the orange frame piece. Most visible at 1:15, they are the gray plastic arms that don't look like they attach to anything. They swing in and hold down the white balance beam and lift it off the knife edge for shipping. The range setting rings may have a spring clip for them to or you can use a piece of foam to keep them from rattling around.
It makes me so happy when you post a new video. I just love all the things you do. I wish I could download all the information stored in your wonderful mind. You are amazing! Thank you, thank you, thank you !
Miss Ron don't throw the balance. We leave to posterity the tools of our past time. Thanks for your videos and thanks also to the lady cat for providing the raw material for the experiment. a warm greeting from Italy.
You have outdone yourself my friend. It is clearly getting to the point where you need some new projects during the shutdown. Thanks for a very interesting video, as always. Appreciated.
I used that exact scale a lot in the 70s/80s with a precious metal user company. If you zero the scale with the paper, remove the paper, add the fleas, you have the tare wt set, then weigh them. You won't have to keep track of the wt. or do math or worry about units, faster.
I do hope you reconsider throwing it away. If there is a local maker space in your area, someone might be interested in taking it off your hands. If I were close enough, I would take it just so I could study the mechanics of it. Or just put it on ebay and offer it for local pickup only and for one dollar.
BTW you should put up this video link on craiglist and some experimenter will probably come and pick it up. Around here people just put stuff out on the boulevard or by their trash with a free sign on it. Your video would help them understand it.
Woah! Don't let too many people know you've got it!!! The US Drug Enforcement Agency takes a very great interest in private citizens who have accurate chemical balances like that :)
Very nice - I live in Germany & the hometown of Bizerba. Mettler Toledo's oldest branch (was once the >160 year old 'August Sauter AG' - aquired by MT in 1971) is just 20km from here. We've got a dedicated 'Museum for Weights and Scales' :)

Have a similar model (Ainsworth Type 12) that reads down to 10 micrograms! They all have a way to lock for transport. Also have a manual for Mettler H30/H31/H34, can scan and share if there's any interest. Very similar to your H33AR.
Ground glass optics don't play well with cameras. You have the same issue when digitising slides or film. I think it's because the ground glass screen is supposed to slightly diffuse the projected image or number, but part of the light still makes it through undiffused, and that's picked up by the camera. It's not a camera problem.
Hi Ron and thanks for this great video. Back in the day I actually have bought several mechanical Mettler balances and have also disposed of quite a many. The circular metal counterweights might actually be something to spare. They are a binary series of high accuracy weights. The largest is 80 grams, then 40, 20, 10 and so on. The precision is unbelievable. They all are far better than 100 micrograms. BTW, you should always close the balance doors before taking the reading.
I read some poop (found it to be LITERALLY poop!) on operating the scale, such as keeping the temperature constant, not touching the container with your hands, closing the instrument doors, etc. DOING EXPERIMENTS WITH IT AT THE MOST SENSITIVE SETTINGS I COULDN'T GET ANY OF THAT CRAP TO MAKE ANY DIFFERENCE IN THE READING WHATSOEVER! The thing that DID make a difference was when I leaned on the table causing the table leg to sink into the carpet thus tilting the scale.
@@glasslinger Thanks for comment Ron. You seem to be lucky as not to have drafts in your shop. I remember we had in the university analytical lab class a task to measure the amount of iron oxide dust, which I failed three times until the tutor came to see my weighing... The lab obviously had very efficient fume removal. Bad memories, that is.
@@glasslinger The axis of gravity is to the center of the earth, at least theoretically. Scale has to stay level for best accuracy. I suppose you can calibrate the span with the reference weights.
There should be shipping pins to lock the bridge located in the upper deck and instructions to place them on a sticker under the cover. I have a slightly later model I still use.
Ron I trust that you are keeping safe. I used one of these in the 70s while studying chemistry. Do not remember a manual, but there was a 16mm movie by Mettler which covered the operation of these instruments. Fantastic piece of clever engineering.
I used one of these when I was a teenager working in a chem and bio sciences lab in the 70s at Washington State University. So very sad to see it go. Thanks for the trip down memory lane!
Wow, that is one complex beautiful piece of precision instrumentation. Such a shame you don't have room or a use for it, I bet the original purchaser never thought for a moment it'd be thrown away so soon. For the price they paid i would think they expected it to be useful for many decades maybe even hundreds of years. Thanks for at least getting it working and showing it in use one last time, appreciate you sharing.
There are a few over at the local standards laboratory, sitting in the mass room. On concrete benches cast into the floor, with a separate isolated slab only for them, so they are stable. Both digital and analogue, so they probably have the full set of manuals for them still. I would guess any local user of them will have the manual, and perhaps try your local university with an engineering department, who might have them in a library, as they almost never throw out manuals for equipment they have had in use there.
Well I Count on you for coming up with something Great this has the be one of the best this takes the Take you Could weigh a flea that's a classic always look forward to your videos Thank you I hope you are safe and your and your family are OK God-bless You thank you from the bottom of my heart for keeping us Entertain
I have a very similar one made by Sartorus. They are fun to play with and use. You should keep it, you probably have more use for it than most people. When making your tubes you can use it to mass out the coating mixtures for the filaments and cathodes, that way you can get more consistent results. If you send me your email, I can send you some pictures of fleas, I took with our electron microscope
Great instrument, I remember those at college on the 70s. That 'sensitivity' is nothing to do with the camera- it's because the ground glass screen is highly directional to boost the brightness of the display. A bit like the modern ATM or laptop privacy screens.
I have a orange colored one I got at an auction where it was labeled "popcorn popper". It is also neat how it can self calibrate itself. I bought a weight set and the scale was more accurate than the weight set.
Miss Ron don't throw the scales. We leave to posterity the tools of our past time. Thanks for your videos and thanks also to the lady cat for providing the raw material for the experiment. a warm greeting from Italy.
I used one in 1970 ( Chemical Technology course)and remembered how the light was used in the display. So touchy, all doors had to be closed to stop drafts from moving the scale. Seemed to me some used polarized light source for some reason..
I do have the cal masspieces that will work on that unit. 5mg with a known mass down to the tenth of a microgram level, though the error bars are in the microgram range
Agreed, how will we ever get the sport taken seriously without weight divisions and a standardised scoring system? Olympic committee won't even meet with us...
@@worstuserever The Olympic committee must indoctrinate the weight standards, if there is to be uniformity in the scoring system, I totally agree with you.
Damn Ron, I was going to open a free clinic for low income fleas! I'm trying to cut costs anywhere I can. I've already got tooth pick splinters for tongue depressors, some threads of glass for syringes and a coffee straw for a stethoscope, but I still haven't figured out how I'm going to do prostate exams.
Ha ha love this. Those fleas will be flea husks though and will have lost all moisture. You can probably double or triple the expected weight..more if they just ate...
I was thinking of building one of these years ago, and I know that the magnetic field is proportional to the current and this is the easiest way to do the knob on the bottom.
This would be electromagnetic force compensation, a really nice principle for a scale. years ago I saw building instructions in an electronics magazine for one. But as I understood, this one is mechanical. they suggested to use an actual speaker for it.
@@terrycooke2756 I can fix that radio for you. e-mail me at eepaul2001 (at) gmail (dot) com I will send you my phone number and address. I have been fixing tube radios, CNCs, robots, plasma cutting machines, and much more. Fixed my first TV in the late 1970s and first CNC in early 1990s.
Ron, thank you for this interesting video. You said the scale could measure 100μg and measured an average weight for the fleas. Since your average weight was 190μg, you could have actually measured one flea! It's a shame that you had to throw it away. Maybe you could keep it until the quarantine is over and then give it to a local viewer? Take care!
She normally doesn't have fleas. I use Revolution flea treatment but didn't put it on her yet this year. She right now has no fleas. I also spray the house and yard.
We usually smoosh our kitties fleas between our finger nails to kill them. So a lot of the wet weight is squished out. I'm guessing you are measuring dry weight of your fleas not living weight.
Dude, you have scores of old radios in your attic not being used and never will be used. You have room for this scale. You never know when you might need it.
Please, tell us, do you teacher of laboratory of some universite? I ask becase you are amasing, and very lovely with your 2 cats. Tell us of your life or biographie. Forgive my bad english. I dont speak english because I live in Santiago of Chile South America. You are very so amazing. For you are not secret of nothing. I see all your didactic videos.
Not sure how old those flea bodies are but I'm assuming they are pretty desiccated. Not sure how you could weigh a live one with all of it's bodily fluids. It would be interesting to know how much the fluids weigh.
I had thought of that myself. But the video is more on "how to do it" rather than making a really accurate measurement. I guess I could weigh the cat to 6 decimal places, then comb out the fleas, then weigh the cat again..... :)
That's really sad, Ron.... I wish I could drop by your place and take it home... but I think the ocean and half a continent between us might make that a bit difficult.
My thoughts too, same problem too though :( Would make lockdown a bit less boring, being able to measure fleas and other similarly lightweight items accurately.
Hello Ron,We have not see any new videos from you & we do not have your contact information.We just want to be sure you are ok in this pandemic time. 73 Malek KI7DYM & JODY KJ7DAC
Hoo boy, poor kitty... I think maybe it was the focal length of the camera or the light coming from the reflective surface, the darkness being the same as a shadow, making it impossible to see
As stated: "I hate to get rid of it like that, I don't have the room to store it, I need the space...I don't have a use for it..." ... So, yes, there is compassion and also the reality of usefulness and need of space. The time was taken to enlighten "us" on this piece of obsolete mechanical history, for that I feel privileged. Thank you Ron! Thank you always!
Have you considered putting it on EBay/Etsy/Kijiji or the like? There is someone out there that would love this, I'm sure. Edit: I took a look - they're not huge money makers, but it looks like you could list it for about $150. That's definitely borderline as to whether it rescues it from a dumpster or not. (Oh, and if you mentioned that in the video, sorry. I skipped ahead a bit).
@@AliasUndercover Same. And the reason I don't have room is because the room I do have has been carefully alocated to massive quantities of other things I didn't have room for and don't need.
The shipping would pass $50 for sure and it is in poor condition, with internal parts missing. It barely works. Someone local stepped up to take it so it will be saved from the dumpster.
Weigh the cat, then remove the fleas. Then weight the cat again :-). I would evict the cat and keep the scale. I do feed an outside cat here that I like very much, so no hate please.
According to other studies: A single cat flea weighs 0.45 to 1.08 mg, depending on whether it has fed or not. They must be hydrated over the couple of days when you tried to collect them. A weight loss of around .. .. pretty near the human body fluid percentage, 60% :)
There seems to be quite a range of flea sizes! I had some that were clearly double the size of others. Maybe different times in their growth cycles or some such. Maybe some just overate!
@@hisheighnessthesupremebeing Annoying ! That I overlooked that. You are right. It's dehydrated. English is not my native language but that's not the reason and I am not sure why I wrote it as that.

Hell, I'd love to have it if I had somewhere to put it. Unfortunately I don't, nor do I need it.
@@AliasUndercover Same. And the reason I don't have room is because the room I do have has been carefully alocated to massive quantities of other things I didn't have room for and don't need.
The shipping would pass $50 for sure and it is in poor condition, with internal parts missing. It barely works. Someone local stepped up to take it so it will be saved from the dumpster.

Weigh the cat, then remove the fleas. Then weight the cat again :-). I would evict the cat and keep the scale. I do feed an outside cat here that I like very much, so no hate please.
The supervisor was burdened by that weight.
According to other studies: A single cat flea weighs 0.45 to 1.08 mg, depending on whether it has fed or not.
They must be hydrated over the couple of days when you tried to collect them. A weight loss of around ..
.. pretty near the human body fluid percentage, 60% :)
There seems to be quite a range of flea sizes! I had some that were clearly double the size of others. Maybe different times in their growth cycles or some such. Maybe some just overate!
@Im True.. Hate to be that annoying guy but.. DEhydrated not hydrated
@@hisheighnessthesupremebeing Annoying !

You are right. It's dehydrated. English is not my native language but that's not the reason and I am not sure why I wrote it as that.
@@imtrue2132 no worries.. It's not like the we didn't get the meaning of what was said
Oh my mind is terrible. I wondered immediately: "how much does a fart weigh?" ... I'm so dumb :|
That must have been an interesting estate sale.
