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.
