True RMS Autoranging MultiMeter

Model RF40C refractometer with automatic temperature compensation measures propylene glycol freeze point from –51 to 0˚C (–60 to 32˚F), ethylene glycol freeze point from –51 to 0˚C (–60 to 32˚F), and the specific gravity of battery acid from 1.10 to 1.40. When ambient temperature varies from 20°C (68°F), readings are automatically adjusted to compensate for temperature variance between 10°C to 30°C (50°F to 86°F). It provides accurate and repeatable measurements on easy to read scales. Only 2 to 3 drops of solution are needed to make the measurement. The prism and lens with simple focus adjustment provide repeatable results. Complete with carrying case and calibration screwdriver.
