Refractometer Engine Antifreeze Battery Coolant Test Propylene Glycol-Detector

Refractometer Engine Antifreeze Battery Coolant Test Propylene Glycol-Detector DESCRIPTION Refractometers provide a fast, simple and accurate of testing and controlling coolant concentrations. -Use a pipette to extract the coolant from the machine. -Using the pipette again, place 2-3 drops of cooling onto the refractometer and carefully secure its cover plate. -Make sure there are no dry spots or air bubbles below the of the cover. -Readthe scale value at the intersection of the dark and light parts, at thepoint where they meet on the scale. It may be necessary to adjust theposition of the light source to maximize the contrast of the shadowlines. -Placing the instrument down and perpendicular to the light source is usually better for the best contrast. -Whenyou're done testing, be sure to dry the lens with a clean cloth (don'twash or rinse it), and place the instrument in the plastic case feature: -Lightweight aluminum construction for durability. -The refractometer is equipped with a measuring scale, -It allows direct reading and is easy to focus and calibrate. -Soft and comfortable non-slip rubber handle -Accurate test results.
