What do you use to measure glycol?
Hydrometers are good options for determining glycol concentration, and they are often chosen because they are inexpensive. However, hydrometers have some disadvantages when compared to refractometers. Hydrometers are made of glass, which is easy to break.
What does a coolant refractometer do?
A refractometer is used to determine a concentration of a metalworking coolant within an aqueous solution. It operates based on the principle of refraction. When rays of light pass from one medium into another, they are bent either toward or away from a normal line between the two media.
What Brix should my Glycol be?
24.75 brix
G&D Chillers recommends a 35% Inhibited Propylene Glycol to 65% water (24.75 brix). Measure the solution using a glycol refractometer.
How do you test glycol?
How to Test Ethylene & Propylene Glycol
- Use CoolTrak coolant test strips (kimdon.com) to test a sample of ethylene or propylene glycol based coolants. Dip the strip in the test substance to indicate the boiling point, freezing point and PH.
- Increase accuracy by using a refractometer.
How do you test glycol in water?
Testing for antifreeze (ethylene glycol) in water is quick and easy. Simply add your sample to the fill line, break the three ampules in order and wait 30 seconds for color to form. If a dark blue color forms in the pouch there is ethylene glycol present in the sample.
How much glycol do I mix with water?
A mixture of about 2:1 water:glycol (around 33% glycol) is often recommended, as this has quite a low freezing point without being too viscous. (Changing the proportion also affects the boiling point of the mixture.)
What glycol is pink?
propylene glycol
This is the preferred glycol used in businesses concerned with safety such as schools, churches or food plants. Visually, ethylene glycol is fluorescent pink while propylene glycol is usually a fluorescent yellow or green.
