Only use distilled water for calibration. Using anything else will result in improper calibration. Even other sources of water for example may result in a calibration which is indistinguishable from using distilled, or it may be way off. It all depends on how pure the water is. Just use distilled water eliminate that factor of uncertainty! It's cheap and very available.
I agree and had always used distilled water. however I have been slacking off recently and For my small system I have not seen any issues using tap water.
I dont change my coolant on a set interval. depends on usage. The water in the coolant evaporates so topping off with water is needed while checking and maintaining your set mixture. this brand works well to keep a nice film on the machine for protection. Check with mfg for health risks each brand has a different makeup. request a MSDS.
After doing a coolant flush, usually some coolant and water is left over in the engine, hoses etc. making it difficult to get the desired 50/50 mix during the refill.Will this tool show if the ratio of coolant to water is off for new coolant.( not 50/50) Also would reverse osmosis water work as well as distilled? Thanks for the video. Always learning something new!!
Yes there will be coolant left over from prior fills. I check the coolant first using the spreadsheet Posted in the video description. this will tell you how much coolant is in the current mix and how much you need to add along with your water. I have found that any water seems to be fine. so Yes reverse osmosis water is fine.
Yes Jeff, you are correct ! A Refractometer measures the RI Refractive Index measured in Brix. I did not say I was measuring the PH I stated the PH levels were off In my coolant which led me to purchase the Refractometer. Which allows me to get the coolant mixed correctly. pH:This value describes the alkalinity or acidity of the coolant.Most coolants are designed to operate in the alkaline range and it is important to maintain pH near the values given on the product data sheet. Low pH generally indicates low coolant concentration, poor coolant mixing or instability, concentrate that is too old for use, or high rates of biological growth. Where pH is high, the coolant has likely been contaminated by high alkalinity materials. There are many factors that go into machine coolant. If your using a water based coolant PH is involved.

Well it's not a $400 unit that's for sure but it is a way to measure the Refraction. Accurate or not you can gauge the amount you add. For a Home shop or small production shop this should be sufficient.
Thanks Sam, that's simpler than I thought.
Hi Craig, Yeah pretty simple

How frequently we should change ? Is there any safety instructions to use and maintain. Is there any health issues working with coolant??

Ok thanks 👍
What do you use to calibrate it if you're using 50/50 premixed coolant, instead of mixing your own? Distilled water still? Thanks!
Yes
Thanks for your information.
Your Welcome

Hi, are we supposed to compare it with refractive index like the abbe's one? Thank you
Yes
Is there any difference between salinity and brix referectometer??and which one is this??
This is a measurement of Brix ( Refractive Index)
Why didn't you measure the Anti-freeze? That was the only reason why we were clicking on your video
My Apologies,
What should I compare it too?
Is it the old coolant (from engine? reading to new mix batch of coolant
Ie to see if the match
yes
Most coolant in machine shops should be between 5 and 7 if your cutting aluminum higher is better. But. 6 is offel low in my opinion.
Yeah I try to stay in the middle around 6
Refractometer measure coolant concentration levels. NOT PH levels.

CNC4XR7, is Techcoplus Refractometer is chines product?
I think so
You need to make a correction (correlation) chart with known concentrations.
Good Idea!
How to calculate value of refractometer index..??
Did you download the Calculator?
Yup.. now???
The mfg. Should list the coolant refractive index for there product.
Thank you so much...😘
what is the meaning of white and blue?
That is the light refraction line
They all come from one factory😂
Yeah most likely
From Azad engineering 😅
thank you
Go buy some 50/50 and test it. I bet it's off because that's junk.

@@CNC4XR7 I want to see if what is in the car is off. If it's not accurate then it's junk.
