Oxygen analyzer has friendly communication menu which makes the operation visual and simple. It could keep working in the air for a long time without affecting the sensor life. The response speed is rapid and the lowest measurable unit is 0.1ppm. Power being supplied at a wide range makes it more suitable for different occasions.
Oxygen analyzer main features:
1.The imported zirconium dioxide sensor is with high measurement accuracy, a rapid response speed and long calibration cycle for features;
2.Only one random point needs to be calibrated among the whole measured range, making the calibration operation simple and convenient;
3.Function of built-in compensation system for temperature could reduce the influence from the changes of environment temperature on the measured accuracy;
4.No reference gas is needed, and the analyzer wouldn’t be affected by the oxygen concentration of working around atmosphere;
5.It could do one-way or bidirectional communication with the upper computer;
6.The imported sampling pump is built in and the working mode can be set through the software.
