cryoscopeIt is a portable detection instrument designed to measure the concentration of battery solution and antifreeze. By measuring the percentage, the freezing point of antifreeze systems based on propylene glycol and ethylene glycol, as well as the freezing point of car front window cleaning fluid, can be determined. It can also be used to check the specific gravity and usage status of electrolyte in lead-acid batteries, providing great convenience for preparing and testing antifreeze and battery fluids. It is suitable for cooling systems of engines and internal combustion engines on various transportation carriers.

It is very convenient and fast to determine the freezing point value of antifreeze prepared by adding additives to ethylene glycol as the base liquid. He is a portable detection instrument designed based on the correspondence between solution concentration (corresponding to freezing point) and refractive index. It can quickly test the crystallization freezing point of ethylene glycol and propylene glycol antifreeze and measure the specific gravity (relative density) of battery water.

　　cryoscopeMain functions

Aim towards the bright direction and adjust the eyepiece's visual acuity ring until the marking line is clear.

Adjustment benchmark: Before measurement, use standard solution (purified water), instrument, and test liquid based on the same temperature. Open the cover plate, then take 2-3 drops of standard liquid and place them on the refractive prism. Gently press the flat cover plate with your hand and see a blue white boundary line through the eyepiece.

Rotate the calibration bolt to align the blue white boundary line in the eyepiece field of view with the reference line (0%)
