Chemical Refractometer can be used to determine the concentration of NMP N-methyl-2-pyrrolidone (NMP) is a chemical base required for the production of lithium batteries. Refractometers can monitor the chemical manufacturing process and maintain the highest quality standards. Chemical Refractometer can also measure hydrogen peroxide (H2O2) concentrations, and the concentration of the ingredient in a disinfectant greatly affects its ability to inactivate or destroy microorganisms. Chemical Refractometer can also detect the concentration of cutting fluid, control the concentration of cutting oil and lubricant, which can effectively reduce the risk of cutting tool damage.
