The Kraft & Dele KD10541 automotive tool set includes a refractometer for measuring fluids in cars, trucks and buses. It measures battery charge, the freezing point of propylene glycol- or ethyl alcohol-based fluids, the freezing point of windshield washer fluid, and electrolyte density.
To take a measurement, use the pipette to place a few drops of fluid on the prism, then close the cover to spread the sample evenly. After waiting approximately 30 seconds, read the result through the eyepiece at the boundary between the white and blue areas. Adjust the focus using the knob behind the lens. Calibrate the refractometer with water and the supplied screwdriver.
