Purity oxygen analyzer uses an imported limiting current sensor with a rapid response speed, high accuracy and long calibration cycle for features. The frame mount installation mode makes it simple and convenient to install.
Purity oxygen analyzer main features:
1.No reference gas is needed and analyzer will not be influenced by oxygen purity in atmosphere;
2.With the functions of compensation and sensor protection built in, the analyzer can be on power under 99.99% occasion without affecting the sensor’s serving life.
3.With the function of temperature compensation, the amount of sample gas flow wouldn’t bring any error to the sensor’s measured results;
4.Altitude measurement module can be expanded to avoid the influence from atmospheric pressure change on the measured accuracy;
5.The measured accuracy of the whole range can be met by a random point calibrated, making the operation simple and convenient.
