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 10oC ~ 30oC ambient temperature.
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, handsome in appearance, easy to use, it is widely used in the automotive industry.
