Digital display high-precision optical instrument designed by refraction principle. Compact and beautiful, it is easy to use and fits easily in your pocket. The LCD large-screen liquid crystal digital display, as long as a drop of sample solution is placed on the prism, it will be displayed within 3 seconds, which can avoid human subjective error in numerical interpretation. It is suitable for the measurement of liquids such as fruit juices, food and beverages.
It has the function of automatic temperature compensation, the number of uses is more than 10,000 times, there is a power-saving function of automatic shutdown, temperature display: Celsius/Fahrenheit conversion, and there is a power alarm function. Different models in the series can display the refractive index, Brix, Brix, salinity, Baumé, convertible, bean paddle concentration, urine specific gravity, serum protein concentration, ethylene glycol concentration, propylene glycol concentration, battery liquid concentration, etc.
