The RHA-787A handheld coolant and battery fluid refractometer can be used to measure the freezing temperature (in ℃ and ℉) of automotive antifreeze based on ethylene glycol or propylene glycol, as well as the specific gravity (SG) of battery fluid. The specific parameters are shown in the following table.
This model is commonly used in automotive maintenance and battery servicing.
The instrument body is made of copper material to maximize measurement accuracy and durability.
It also has an Automatic Temperature Compensation function (ATC), which can provide accurate readings at different ambient temperatures.
