Digital Portable Refractometer for Antifreeze, Ethylene Glycol, Propylene Glycol Quality Choice

digital portable refractometer for antifreeze, ethylene glycol, propylene glycol 

The refractometer can be used to check the antifreeze of the freezing point in the cooling system before winter comes. It can be very convenient for quick determination of glycol-based fluids and additives preparation of antifreezing fluid freezing point values. Dual-use of antifreezing fluid freezing point and battery fluid specific gravity test is depending on the concentration of the solution (corresponding to the freezing point) and the refractive index of optical instrument designed for correspondence. The instrument can be a quick test of ethylene glycol and propylene glycol antifreeze fluid freezing point and measure the proportion of battery water of crystallization (relative density). Can also be used for the car's cooling water, refrigerant fluid with antifreeze.

Features: 

1. Adopt principle of refraction design 

2. Digital Display 

3. compact, able to fit into a pocket. 

4. Fast and easy: only need a drop of the sample solution, placed on the prism, readings within 3 seconds. 

5. widely used for measuring almost any fruit juice and other food and beverage liquid.
