automotive freezing point instrument detection of antifreeze glass of water freezing point VBC4T Warming-up freezing point meter Accuracy of temperature range Antifreeze freezing point: -50 ° C ~ 0 1 ° C ± 1 ° C The specific gravity of the battery liquid is 1.10 to 1.40 and 0.01 to 0.01 Glass freezes from -40 ° C to 0 ° C ± 5 ° C The instrument can measure the antifreeze and glass cleaning agent freezing point, the proportion of lead-acid battery electrolyte. Temperature compensation device is included to ensure the measurement is simple and convenient, to ensure accurate measurement in the ambient temperature of 10 ° C ~ 30 ° C The basic principle is to use the total reflection critical angle method to measure the refractive index of the solution, and then calibrate the measured liquid concentration and its performance. Because of its principle of reliable, accurate to meet the actual needs, there are small size, light weight, light weight, handsome in appearance, easy to use, it is widely used in the automotive industry. The basic parameters is the instrument can measure the antifreeze and glass cleaning agent freezing point, the proportion of lead-acid battery electrolyte. VBC4 common type: Before using the need to use distilled water calibration zero. VBC4T Warm-up type: with temperature compensation device, to ensure the measurement of simple and convenient, to ensure that the 10oC ~ 30oC ambient temperature measurement accuracy. Field of View Description: ETHYLENE GLYCOL: Ethylene glycol antifreeze freezing point. PROPYLENE GLYCOL: Glycerol type antifreeze freezing point. BATTERY FLUID: Electrolyte specific gravity. (1.15 ~ 1.20 to be charged; 1.20 ~ 1.25 enough power; 1.25 ~ 1.30 sufficient power) CLEAN: glass cleaning fluid freezing point Third, calibration 1, open the cover with a soft flannel cover and prism surface wipe clean. 2, the distilled water drops on the surface of the prism with a straw, close the cover gently press, the freezing point tester to the bright place, rotating the eyepiece to clear the visual field within the groove. 3, adjust the calibration nails, so that the light and dark line can be coincident with the baseline. Fourth, operation 1, open the cover with a soft flannel cover and prism surface wipe clean. 2, the liquid to be measured drops on the surface of the prism, close the cover gently press the ice point tester to the bright place, rotating the eyepiece to clear the line of sight within the field of view, read the light and dark boundaries in the reticle Corresponding to the value on the scale can be. 3, the test is completed, with a soft velvet cover plate and prism surface wipe clean, clean straw, the instrument stored in the box. 4, in the measurement of battery fluid, be careful not to sprinkle on the skin and eyes, to prevent burns, carefully wipe the instrument after testing. 5, Annex: manual, screwdriver, pipette, clean cloth. Sixth, note: 1, not in the relative humidity of more than 85% of the ring mirror in the long-term placement, so as not to affect the optical system. 2, do not get into the liquid and water adjustment knob and eyepiece, so as not to damage the internal components. 3, do not leap and collision, so as not to damage the instrument accuracy. 4, immediately after use with a clean cloth to the prism and the refractive plate wipe light net.
