Handheld Car Antifreeze Refractometer, Battery Fluid Specific Gravity Measurement with Ethylene Glycol and Propylene Glycol Scales for Automotive Battery Engine Coolant

Features:

- Function: Measures freezing point of glass cleaning solution, antifreeze (ethylene glycol and propylene glycol), and lead-acid battery electrolyte

- Temperature compensation device for accurate measurement in the range of 10°C to 30°C

- Uses the total reflection critical angle method to measure the refractive index

- Small size, lightweight, and easy to use

- Widely used in the automotive industry

How to Use:

- Place the instrument in an environment with a temperature between 10°C and 30°C

- Measure the freezing point of antifreeze and glass cleaning agent by using the total reflection critical angle method

- Measure the proportion of lead-acid battery electrolyte

- Ensure not to place the instrument in an environment with relative humidity over 85%

- Avoid contact of the liquid and water adjustment knob and eyepiece

- Handle with care to avoid damage to the instrument's accuracy

- Clean the prism and refractive plate after use with a clean cloth

Specifications:

- Ethylene Glycol: -50°C to 0°C (0% to 70%)
