Can coolant freeze protection be measured with a refractometer?
Refractometers can measure both Ethylene and Propylene glycol based coolant/antifreeze very accurately. Automatic Temperature Compensation is an absolute necessity for refractometers. Without it, refractometers can easily be inaccurate by more than ±16°F.
What does a refractometer measure in coolant?
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.
How do you calibrate a refractometer for coolant?
To calibrate, just make sure the prism is clean and place a few drops of tap water on the prism. The separation line should be on zero. If not, turn the adjustment screw until it is. Remember, refractometers read on a Brix scale rather than actual percent.
What’s the best antifreeze tester?
- Editor’s Choice: Prestone Antifreeze/Coolant Tester (AF-1420)
- OEMTOOLS Professional Series Antifreeze Tester (24507)
- Best for Cold Climates: SMARTSMITH Antifreeze Refractometer.

- ABN Deluxe Antifreeze Tester.
Is a refractometer better than a hydrometer?
Is a Refractometer More Accurate Than a Hydrometer? Well, neither is more “accurate” than the other, they function very differently. A refractometer measures the amount of sugar in your solution via “refraction” of light, when it passes through the wort sample.
What tool is used to check the freezing point of coolant?
The antifreeze hydrometer is used to measure the freezing point of the cooling system. Fill the hydrometer by squeezing the rubber bulb on one end while the other is inserted into the coolant. Make sure to fill the hydrometer completely.
How do I check the pH level in my coolant?
Propylene glycol coolants may be tested with a paper test strip. The test strips are dipped into the coolant and then the color of the strip is matched to the chart to determine the condition. This method measures the pH of the liquid, an indication of the acidity level.
How accurate are antifreeze testers?
Sealey Propylene Glycol Antifreeze Tester AK4122 review Results were consistently around four degrees high, regardless of the concentration. It’s not cheap or completely accurate, but choices are limited if your car uses propylene glycol antifreeze.
How do I know if there is antifreeze in my 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.
