The antifreeze refractometer are designed for testing for concentration of the battery fluids, antifreeze liquid and cleaning fluids. With the indication of the percentage you may know at temperature the fluid will be frozen for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electroly te solution batteries. The model marked with ATC means it has Automatic Temperature Compensation.
Monoethylene glycol and mono propylene glycol are used extensively as antifreeze in closed cooling systems . Dose concentrations vary dependant upon the level of antifreeze protection required (C or F). Refrigeration units and engine cooling systems use glycol in concentrations up to 60% v/v to maintain coolant fluidity at low temperatures.
If customers prefer to have a model which has (C) and (F). The model RHA-600ATC is good choice as the temperature in C and F were both lised in its scale! It has three scales for Glycol analysis / testing and Battery liquids testing:
The Glycol analysis / testing scale offers a convenient, fast and accurate way for testing / analyzing the glycol concentration of engine coolants and other anti-freeze solutions.
The Battery Specific Gravity Scale offers a convenient, fast and accurate way for testing the batery's liquid Specific Gravity.
The RHA-600ATC has Automatic Temperature Compensation System.
