Refractometer use for antifreeze and refractometer factor for Volvo Coolant

[iamhives]

A bit of an obscure question but I know there is a wealth of knowledge on this forum..

I already own a Brix Refractometer like this https://www.amazon.com/dp/B01LW2ZU6R/re ... in_0_title

It measures the specific gravity of a liquid. I originally bought this for my brewing/baking hobby to measure the sugar levels in liquids (BRIX) but it seems that it should be able to be repurposed to measure the specific gravity of antifreeze and battery acid. I believe the exact same device is sold for measuring antifreeze. I think the only difference is the scale. Anybody have any idea on how to calibrate and/or use this for antifreeze. Doing a bit to research I find the following

"Each coolant has its own refractometer factor which can be found on a product data sheet or determined
using known sample concentrations. This refractometer factor can be multiplied by the °Brix reading taken
from the refractometer to ultimately obtain the coolant concentration.
% Concentration = (°Brix Reading ) x (Refractometer Factor)"

Anyone know what the Refractometer Factor for Volvo coolant (or other similar coolant). I've found data sheets but they seem to focus on the health effects of coolant. Seems that if I had that then I could use this to convert the BRIX reading from my current refractometer to % Concentration for coolant.

Of course I could just buy a cheap version intended for antifreeze - but that would be no fun (and a waste of resources)

Try to buy the fresh Volvo coolant (or other recommended coolant) and test it to determine the proper reading on your refractometer. Carefully reduce the concentration with distilled water and test to determine the factor.

Repeat with battery acid and brake fluids.

Let us know the experimental results. Great idea.
