Portable Handheld Refractometer Gravity Analyzer


SKU: SYM1622440691 Category:


Handheld freezing point detector, also known as refractometer, freezing point tester or automobile freezing point tester, is designed to measure the freezing point of antifreeze liquid, glass liquid and the proportion of battery solution. As long as a few drops of liquid are placed on the prism, and then observed toward the light, the measured value of the solution can be quickly read out. The freezing point of the anti-freezing system based on propylene glycol and ethylene glycol and the freezing point of the car front window cleaning liquid can be known by the measured percentage. It can also be used to check the proportion of electrolysis in the battery and the state of use.
