Handheld Antifreeze Refractometer ATC for Antifreeze Freezing Battery Fluid

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.

Product Description

The handheld antifreeze and battery fluid refractometer is widely used in car maintenance, repair workshops, and battery servicing. This tool helps ensure proper coolant protection in cold climates and accurate assessment of lead-acid battery charge levels.

The RHA-800A model handheld antifreeze and battery acid refractometer has two functions:

  1. It measures the concentration percentage and freezing temperature (in ℃) of both ethylene glycol and propylene glycol based automotive antifreeze. The readings indicate the concentration of the measured solution and the temperature at which it starts to freeze.
  2. It measures the specific gravity (SG) of battery fluid. Specific gravity is the density ratio of battery fluid to water, which is used to indicate the charging state of lead - acid batteries. The higher the specific gravity value, the more fully the battery is charged.
