Extech RF40 Portable Battery Coolant/Glycol Refractometer with ATC (°F)
Portable Battery Coolant/Glycol Refractometer with ATC (°F)

This portable battery-powered coolant/glycol refractometer is simple to use and provides precise and reproducible measurements on easy-read scales. The RF40 detects the freezing point of automotive coolants (propylene glycol and ethylene glycol), determines the specific gravity of battery acid, and gives a rapid reference to battery charge status. Includes one-year warranty, case, calibration screwdriver, plastic pipette, and calibration solution.
