Automotive Coolant Refractometer ATC, Coolant Tester for Ethylene, Propylene, Battery Fluid

The RHA-200A model handheld antifreeze and Battery acid refractometer measures the freezing point temperature (in ℃) of ethylene glycol or propylene glycol based automobile antifreeze, and the specific gravity (SG) of battery fluid. The specifications of these measurement scales 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.

-60℃ to 0℃ 5℃ ±5℃
Propylene -50℃ to 0℃ 5℃ ±5℃
Battery Fluid 1.100 to 1.400 SG 0.01SG ±0.01SG



Product Description

Handheld antifreeze and battery fluid refractometers are widely employed in automotive maintenance, repair workshops, and battery servicing. These tools play a critical role in ensuring proper coolant protection in cold environments and accurately evaluating the charge status of lead-acid batteries.  

The RHA-200A handheld antifreeze and battery acid refractometer offers dual functionality:  

  1. Antifreeze Freezing Point Measurement: It determines the freezing point (in °C) of ethylene glycol or propylene glycol-based automotive antifreeze. The reading reflects the temperature at which the tested solution will start to freeze, making this model ideal for use in regions where temperatures do not fall below -60°C.  
  2. Battery Acid Specific Gravity (SG) Measurement: It measures the specific gravity of battery acid, a parameter that compares the acid’s density to water and indicates the charge state of a lead-acid battery. Higher specific gravity values signify a more fully charged battery.
