The oxygen analyzer is a purely physical measurement, no reference gas, no consumption of chemicals and electrolytes. The instrument has high precision, simple operation, can be used after ventilation, and the measurement is quick. It only needs to connect the inlet of the instrument to the outlet of the sample gas, and the oxygen purity value can be displayed within five seconds.
The working principle of the high oxygen analyzer is as follows:

br/ Charale of Nitrox Analyzer:
The sensor has a built-in method, convenient for users to install and use; the integrated sensor temperature compensation circuit avoids the influence of temperature changes on the measurement accuracy;
The altitude measurement module can be expanded to avoid the influence of atmospheric pressure changes on the measurement accuracy; the sensor is not poweredNo consumption, long life, easy maintenance, etc.;
No reference gas is required and it is not affected by the oxygen concentration in the working environment; imported limit current sensors are adopted, with fast response speed, high precision and long calibration cycle. Long-term functions;
Built-in compensation function and sensor protection function, the analyzer can be turned on in 99.99% of the environment and will not affect the service lifeof the sensor;
Embedded installation makes installation easy and convenient; built-in temperature compensation function, the size of the sample gas flow does not cause errors in sensor measurement;
Calibration at each point can cover the entire range. Excellent measurement accuracy, simple and convenient operation.
The high oxygen content analyzer is widely used in large-scale air separation of high purity oxygen, medical and industrial oxygen generators, smelting industry, medical and healthcare, petrochemical, environmental protection, Used in electronic power supply and other industries with real-time detection analysis for high concentration oxygen.
