Honey Refractometer with ATC Refractometer for Honey Moisture Measurement Portable Antifreeze Multifunctional Freeze Point Measuring Device

The portable antifreeze freezing point meter, also known as an optical freezing point meter, freezing point tester, car freezing point meter, antifreeze freezing point meter, or antifreeze freezing point tester, is designed to measure the freezing point of antifreeze, glass fluid, and battery solution. Simply place a few drops of liquid in the prism and hold it up to the light to quickly read the measured value.
ADVANCED AUTOMATIC TEMPERATURE COMPENSATION TECHNOLOGY (ATC): Automatically adjusts to compensate for temperature, making it even easier to obtain fast results.
SIMPLE USE: Use the dropper to take a sample of the liquid and place it on the prism.The allowable measurement error is +/- 1-3 cm.
