This refractometer has been developed for use in checking battery acid, antifreeze, washer fluid and AdBlue. With the indication of the percentage scale, you can read at what temperature the liquid will freeze. This applies to both propylene, glycol and ethylene glycol. It can also be used to check the strength of electrolyte solution batteries as well as measuring the concentration of AdBlue® 30-35% ATC (Automatic Temperature Compensation), for fast, safe and precise measurement.
