Detection Principle
Chu Yi Measurement and Control*Concentration tester，*Online refractometerUsing the principle of refraction to measure the refractive index of a solution, the refractive index is related to*The concentration of the solution corresponds to *. Obtain the actual concentration of the solution through conversion. This measurement principle has good stability and high accuracy, and is suitable for pipeline installation or container wall installation, as well as other installation methods; The instrument has a compact structure and is easy to operate;
Chu Yi Measurement and Control*Concentration tester，*Online refractometer24-hour real-time online monitoring is possible*Concentration; It has factory linear calibration and automatic temperature compensation functions, as well as online prism automatic cleaning function.
online*Concentration DetectorAdvantages:
1. Online continuous testing eliminates the need for frequent manual sampling and laboratory testing, saving a lot of manpower and financial resources
2. Eliminate manual detection errors and ensure product quality
3. Continuous measurement, rapid feedback, and improvement of product quality
4. Improve the degree of automation, and the relevant concentration data can be connected to the central control room through networking
