Handheld Antifreeze Refractometer with ATC for Coolant Concentration

The RHA-800A handheld antifreeze and battery fluid refractometer measures the concentration percentage and freezing temperature (in ℃) of automotive antifreeze, and the specific gravity (SG) of battery fluid. The measurement 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. This model has Automatic Temperature Compensation (ATC). Models without ATC are also available at a lower cost.   Measurement Specifications Scale(s) Measurement Range Resolution Accuracy Antifreeze -0 to 100% 5% ±5% Freezing -60℃  to  0℃ 5℃  ±5℃ Battery Fluid 1.100 to 1.400 SG 0.01sg ±0.01sg
