Thank you , I'm glad I found this video , I just bought a pH meter didn't know you needed a solution to calibrate, and Im happy to find out it's an easy fix/replacement with baking soda
Glad to know, that I was able to help - thanks for the positive feedback! 💖
Thanks now I can feed my weed without any anxiety
Feed the weed?
@@allcheckout Im high XD
@@skooria8093 lol
Full fat Milk is 6.3 to 6.5 ,cup of black coffee will be 5ish . If I'm out of buffer and I'm unsure I'll cal to 6.4 in milk and check in coffee, I've checked it to a buffer and been .1 out eveytime ,mix your feed to 6.7 you should be good
For soil obvs
I just bought a hanna ph checker. I was going to return it because the solution packets are crazy expensive and they say you have to store it in solution plus their cleaning solution. I am suppose to calibrate it in ph buffer 4 and 7. How can I calibrate with this or a cheaper way? Or is this just to verify that your ph meter is working? For my salt water aquarium.
i use white vinigar it is always at 2.5 so if i put the meter in the vinigar and it sez different than i just calibrated to 2.5
Oh, cool - didn't know. Is it the same with every brand? The thing is just ... I need it to test the pool PH and 2.5 is way off and so the 7.9 is much closer to the optimal swimming pool PH and hence I think it will be more accurate. Just my thinking.
@@allcheckout u dont need 2 buffers?
@@Ic_truth Why would you need 2 buffers? For different PH levels?
@@allcheckout im needing to to from regular 6 or so to 10.78 my ph sick is new. Just the small yellow handheld one. It came w 2 buffers. I already calibrated it w the 7ph buffer. It came qith 2 packets...was i supposed to buffer to calibrate with both?? And everytime i use it?
@@Ic_truth OK - I'm somehow able to remember the two buffers, but not in detail. So one is PH 7.0 and the other one is what PH?
When it's perfectly adjusted, usually it stays for quite some time. I used it for checking PH in our pool (which should be between 7.2 and 7.4) and so I used the test-strips from Clorox and additionally this meter to double check and do fine-tuning. Just re-adjusted every 6 months or so. What are you planning to test?
Hi i have read if you mix 1g potassium chloride per 100ml ph4 buffer solution (you can use ph7 buffer but ph 4 is best as i guess potassium chloride raises the ph slightly) you can make your own cheap KCL pH Probe Storage Solution (3 Molar KCL) ? Have also read leaving 3M Kcl out in open is okay for 2-3months but then needs replacing if your storing a ph probe pen in it (which is best way to store ph pens as there is gel on the glass bulb that dries out quickly). Tap water leeches ions from the pen. Reverse osmosis water is even more worse than tap water.
Very interesting - thanks for sharing here! 👍
Unfortunately I don't need this any more because I don't have a pool any more :-(((
The tap water mixed making soda ph depends on your city and county , basically where they get water . I would still rather use the green solution
Thanks - somehow right and also wrong. Yes, the city water can have different PH, but it won't matter regarding this because if has very very very few alkalinity ... ;-)))
@@allcheckout understood makes sense
@@ImakeITHappEN510 Thanks. If you have something with high alkalinity and something with low alkalinity the one with high alkalinity will "win" - the other one won't matter ... ;-))
I must be to high right now ill come back later thanks
OK thanks
This seems really arbitrary. Although my chemistry exp is minimal. Shouldn't these measurements of both BS and tap water be more exact in order to say that this mixture should yield a ph of 7.9?
I'm still doing it same way and it works perfectly. Every now and then I double check and it seems it's still in sync. If you don't like it - don't use it. Don't see the problem. The water has no effect anyway because BS has high alkalinity.
I wasn't knocking it. Just wasn't sure of it. (even gave a disclaimer about my minimal chemistry experience).
potassium citrate and potassium carbonate should be used to buffer and calibrate the ph. up or down using a solution of known ph.
Interesting - thanks for sharing here! 👍
What's a cheap way to store the ph meter do i have to buy the storage solution do you guys have other ideas
What's not good with this solution?
Store in KCl solution, 1 to 3 mole. Mix 125 grams of Potassium Chloride in 1 Liter of distilled water. This will give a little over 1 1/2 mole solution. Place the electrode in the solution. This helps the electrodes from being depleted of ionic viability.
From what i understood is you put any amount of baking soda, the amount that will dissolve in water is only enough to get to 7.9 the rest will not dissolve, is that correct??
I think everything will dissolve, but not change the PH any further. Should stay at 7.9, but never tried with huge amounts
please i honestly need to know what power i can use when i can not afford the buffer powders and the baking soda.. i need more substitutes for this.
Baking soda is super cheap ... at least in the countries I know. Is it expensive where you live?
DAMN, even with rabid inflation in 2022 a box is less than a USD. Prior to 2020 I was paying 35 cents per box of generic store brand baking soda.
so no need to heat in oven ? i did this just now 12/04/2018 and my meter reads between 8.2-8.3 how do i calibrate for testing water runoff ?
Why would you want to heat in oven?
th-cam.com/video/5IUMRvJe6CY/w-d-xo.html i don't know but other people recommend it to get a neutral reading ?
No, you won't get neutral (PH 7.0) reading. PH of soda ash is about 11.4. I don't see the point, why ppl would try to make soda ash instead of this, especially when you went it to calibrate it for your swimming-pool (PH 7.2 - 7.4), because PH of normal baking soda is much closer to what you want.
Yes ... water with a decent amount of baking soda will always be 7.9, so put your meter into the water / baking-soda mix and adjust to 7.9 ;-)
thank you for your advice and great job on your video :)
So, I’m still none the wiser on how to calibrate my ph pen using the baking soda. Thanks for showing me how to check a liquid solution with an un calibrated ph pen
OK at least something ... hahaha
I think he is establishing the baking soda in water will equilibrate around 7.90 ph. So I think he is saying if it reads 7.90 or very close in baking soda water, consider it calibrated. If not, turn the screw he showed at the back.
@@CuriousEarthMan you can only use this method on meters that allow that manual calibration. Some just set it automatically to either 4, 7 or 10
These pH meters should be calibrated every time one use them... Also keep the probe wer in cleaning solution to not letting it dry. The meter should also frequently be used... These are not toys and require quite a lot attention.
Thanks for sharing here! I never had any problems like that with this device during 4 years of self-made pool maintenance.
Can you use distilled water to calibrate the ph pen?
Very good question. In theory YES, but distilled water is almost never 100% pure, especially after opening the bottle. Additionally to have a reliable reading the alkalinity should be very high and the alkalinity of distilled water is super low. Hence I will still go with the baking soda ... but thanks anyway ;-)
Bro the soda has to be cooked or backed for two 3 hrs I use stove low minimum heat and cook the fumes are co2 to open windows then test I have had readings as high as 10 11
Interesting - thanks for sharing here! 👍 For me it seems to work also without that, but maybe just luck ... haven't repeated yet ...
Heating baking soda makes it transform from sodium bicarbonate into sodium carbonate, which is a stronger alkaline salt. Baked baking soda is useful for applications in which a strong alkaline salt is required, such as in making ramen noodles.
@@generalawareness101 interesting - thanks for the info
Hey guys! There any kind of buffer solution (homemade) to orp meters? thx!
This is homemade ;-))))
It's probably best to use reverse osmosis water or distilled water so there are no impurities that can encourage hydrogen as the solution ages.
No objections, but then make sure you put some artificial minerals into the water as well ...
Reverse osmosis water drops to ph5 when it is exposed to air for a few days
@@kurtwauters6159 add potassium hydroxide, if this happens.
@@allcheckout I use Himalayan rock salt as it contains 80 trace minerals and a little bit of lime juice.
@@obviouslytwo4u Thanks - I love Himalayan salt ... for the color ... lol. Is it really healthy ...? Not so sure when you check where and how it's obtained ....
it wont read 7.0 unless your water temp is at 25c it says on bottle. the meter will be accurate at that temp thats why it is shifting reading
Interesting - thanks for sharing here! 👍
This is why I found some cheap meters that have ATC (automatic temperature compensation). Rock steady regardless of the water temp because here the water temp could be 10c all the way up to 45c depending on the time of year, if in the sun, and how much of it there is. I don't want the hassle of trying to get my water precisely 25c per test.
I've got an idea. Get a bottle of mineral water and usually label says the pH of the water and calibrate your meter accordingly.Hey! don't forget to drink rest of the water. Problem solved. What do you think guys?
Thanks - definitely not the most awful idea. Will definitely try. The only problem could be that it's not a 'buffered' solution and hence anything can affect the ph value easily (e.g. remainders from dishwasher)
@@allcheckout Totally lost you. Remainders from dishwasher in bottled mineral water! If rocket science precision required for hydroponics, you better ask NASA
@@shafiqrheman337 To measure the water with the ph meter you have to fill it into something ... usually a glass ... cleaned by a dishwasher .... but could also be a one-way plastic cup ... for sure much better for this purpose ;-)
I believe Baking Soda has a pH of 9
The internet has about 1000 different answers to that unfortunately. For me it was always 7.9
8
you should of used bottle water as well as tap water with the BS so to show it will always go to 7.9 no matter the water source. people have different water in different places.
I just did it and mine come to 8.6
Thank you meter is defective
There's no difference whatever water you take. It's all about alkalinity. Do your research!
i was thinking the same thing. its only about two months since I bought it on amazon. it was perfect the first three times but then I had to calibrate it. will it act up if the batteries are getting weak. I left it on one night for about 24 hours or more. I also just tested my tap water on its own and it came out to 9.6. it never ever reached that high before. our water is actually really good. when I did my nute solution it was all over the place. it must be shot. one more question. do you have to use both of the packs of calibration solution when you calibrate. I never used the pk with 4.01. was I supposed to.
Sorry, can't remember exactly. I think I bought the liquid calibration on Amazon right away and was using this before I found this solution. It is somehow strange. My PH meter usually works perfectly, but sometimes fails completely, so I'm always checking additionally with PH test strips to double check results.
I thought baking soda has a ph of 8?
There is lots of misleading info in the internet
Being a logarithmic value 0.1 is a lot.
definitely
If you don’t use distilled water is it always going to come to 7.9
What do you think is 7.9? Regular tap water?
Well for example if my tap water is at a ph of 8.7 before I add baking soda and your tap water is at a ph of 5.7 before you add baking soda do you think the ph will always be 7.9 after the baking soda is added?
Very good question and the answer is:
YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES YES
Because it has a very high alkalinity !!!
Cool man I appreciate the help I will try this tomorrow to see how accurate my meter is
@@TheKeithmasterflex Did you try it now?
Ph of baking soda is around 8.3 to 8.4
There seem to be different opinions on that ... Maybe there are differences regarding the brand as well
@@allcheckout Yes, I bet so because I noticed this a few years ago as Arm and Hammer listed bicarbonate first then sodium whereas the generic store brands were sodium first then bicarbonate. On the boxes the percentage of bicarbonate in A&H was higher (the reason that ingredient was listed first) than the generic store brands as well. If I remember right it was 2% to 3% more bicarbonate in the A&H which means less salt (sodium) than the generic store brands. I was looking for heartburn reasons as I need the bicarbonate not the sodium more.
@@generalawareness101 very interesting - thanks for sharing
A little secret, distilled water is always neutral........
But has zero alkalinity and hence almost useless to calibrate
@@allcheckout
I just use it to know where my pH meter is at if it's 10 points over then I always know to pH 10 points - (if my goal is 6.5 then my ph meter should read 7.5) - higher than my Target goal, hope this helps somebody( please help support my page I just started it) my boy got cracked by the police a year ago he got 6 years( because he had some poppy plants in his indoors garden here in the 702) he gave me over 200 pack of new and old strains/magic beans so the menu is going to get very interesting, if you help me promote my channel I'll send you some beans(u have my word) Hosanna El Elyon,, Shalawam Ahch🖖✌🖖✌(702 out).........
@@the_dude_grows7392 "Baking soda is an alkaline substance". Period! If you generate 4.5 PH with something then it's NOT baking soda or you start with a PH value much lower which would be very strong acid!
Actually, distilled water absorbs CO₂ from the atmosphere. Each CO₂ molecule combines with an H₂O molecule to create an H₂CO₃, or carbonic acid molecule. Depending on atmospheric pressure and how long the water has been exposed to it, the pH could be anywhere between 5.8 and 7.0. That's why buffer solutions are used to calibrate pH meters. Buffers resist pH changes from environmental factors.
Same as trying to ph ro or distilled. You cant
For anyone looking for the answer.
Baking soda in non RO water has a pH of 7.9
There, saved you 6 minutes 42 seconds.
Interesting - thanks for the feedback!
Well, ain't you just the little party pooping bitch?
you used tapp water en it must be demineralized water
Won't matter much - it's a high alkalinity product
Bot gonna get that time back.......
Nope
baking soda is 9
If you say so .....
@@allcheckout yeah I am say so
😂
Ahhh um like ahhhh you know your actual time to time.
Ph of baking soda is 9.0 not 7.9 so your meter is off by One point One points
Do you have a link for that?
Take this down
Proof me that it's wrong
Yeah that helped. NOT
ok
