The RHA-504A handheld coolant and battery fluid refractometer is used to measure the freezing point temperature (in ℃) of automotive antifreezes based on ethylene glycol or propylene glycol, the freezing point of windshield cleaning fluids, and the specific gravity (SG) of battery fluids.
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.
This model has Automatic Temperature Compensation (ATC). Models without ATC are also available at a lower cost.
