4 in 1 Automotive Antifreeze Refractometer Car Urea Fluid Tester Battery Freezing ATC Detector Handheld Electrolyte Hydrometer

[xlmodel]-[custom]-[8888] Multi-functional freezing test The handheld refractometer is a small precision optical instrument that measures the concentration and freezing point of the solution. It is the basic principle that the refractive index of the solution is measured using the total reflection critical angle, and then the concentration, freezing point and performance of the measured solution are determined. Main Uses: Measurement of freezing point of antifreeze, proportion of electrolytes of leadacid batteries and glass water freezing point The main technical temperature supplement type, with a temperature compensation device to ensure normal measurement at 10 ~ 30 CRange of measurements Minimum Scale Size net weight Range of measurements Minimum ScaleAntifreeze Freezing point:50~0C 1 30*40*160 95gBattery fluid Specific gravity:1.10~1.40 0.01Glass water Freezing point :0~40 C 5Car urea Concentration :30~35C 0.2%Size :30*40*160CM net weight: 95g Mainly used for Used to measure the freezing point of ethylene glycolas base, while measuring the freezing point of ethyleneglycol and measuring the weight of battery solution.Only a few drops of ethylene glycol on the prism arerequired for measurement, and then the freezing pointof ethylene glycol antifreeze can be read by observation.   Field of view1.Middle ruler:(ETHYLENE)Ethylene glycol antifreeze freezing point (PORPYLENE)Propylene glycol antifreeze freezing point2.Left ruler:(BATTERY) Specific gravity of battery fluid 1.10-1.20 Charge RECHAGE 1.20-1.25 Enough power FAIR 1.25-1.40 Full battery GOOD3.Right-side ruler: Freezing point for glass cleaner4.Upper right ruler: Car urea concentration ruler: 30~35% is the best in 32.5%Warm tips The multifunctional freezing point meter can not measure the freezing point of methanol antifreeze and methanol glass water. Product Calibration Steps   Note: Before testing, the tester needs to be corrected!Step 1: Take one or two drops of distilled water or pure water droplets and cover the surface of the prism.Step 2: Adjust the correction button until the blue- white junction line coincides with the 0C benchmark line Method of use of products 1, lift the cover plate with a soft velvet cloth to clean the cover plate and Prism surface. 2, the liquid to be measured with a straw on the surface of the prism, close the cover plate gently press, the freezing point tester to the bright place, rotating the eyepiece to make the field of view engraved lines clear, read the light and dark dividing line in the division board The value on the corresponding ruler can be  Use caveats Please read the instructions carefully when using the instrument 1. When measuring methanol solution, be careful not to spill on the human body so as not to damage the body after the test carefully wipe the instrument. 2. After use, it is forbidden to use tap water to wash directly to avoid entering the optical system. 3. Avoid falling and other strong impact on the instrument or its large external force      [xlmodel]-[photo]-[0000]
