Coolant Rrefractometer, Automotive Coolant Meter ATC for Battery Fluid, Celcius and Fahrenheit

Product Description

The handheld coolant refractometer is widely used in car maintenance, repair workshops, and battery servicing. This tool helps ensure proper coolant protection in cold climates and accurate assessment of lead-acid battery charge levels.

The RHA-501A model handheld antifreeze and battery fluid refractometer is an universial tool that has its temperature scale in both °C and ℉. It has two functions.

1. It measures the freezing point temperature of ethylene glycol- or propylene glycol-based automobile antifreeze in both °C and ℉. The reading indicates the temperature at which the tested solution will begin to freeze. 
2. It measures the specific gravity (SG) of battery acid. Specific gravity is the density of the acid compared to water and indicates the state of charge of a lead-acid battery — higher sg means the battery is more fully charged.
