Automotive Coolant Tester for Ethylene and Propylene Glycol Fluids

The RHA-100A model handheld coolant and battery fluid refractometer measures the freezing point temperature (in ℉) of ethylene glycol or propylene glycol based automobile antifreeze, and the specific gravity (sg) of battery acid. The specifications are listed in the table below.   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 Ethylene  -84℉ to 32℉ 5℉ ±5℉ Propylene -60℉ to 32℉ 5℉ ±5℉ Battery Fluid 1.100 to 1.400 SG 0.01sg ±0.01sg
