The RHAN-504A handheld coolant, DEF(Adblue) and battery fluid refractometer measures the freezing temperature (in ℃) of ethylene glycol or propylene glycol bsed automotive antifreezes and windshield cleaning fluids, urea concentration in the viechle's DEF, and the specific gravity (SG) of battery fluids. 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.
