The RHAN-747A handheld antifreeze and DEF(Adblue) refractometer measures the freezing temperature (in ℃) of automotive antifreeze based on ethylene glycol or propylene glycol, the urea concentration in DEF (Adblue), and the specific gravity (SG) of battery acid. The specific parameters are shown in the following table.
This model is a universial tool that 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 for a lower cost.
