Embedded oxygen analyzer has a friendly man-machine dialogue menu, which is intuitive and convenient to operate. The measurement does not require a reference gas and is not affected by the oxygen concentration in the working environment. It can communicate with upper computer in one way or two ways.
Embedded oxygen analyzer main features:
1.320×240 graphic dot matrix color LCD display, the display is delicate and clear;
2.Original imported zirconia sensor, high measurement accuracy, fast response, long calibration period, etc.
3.Built-in original imported sampling pump, long life and reliable operation;
4.RS232 (default) or RS485 data communication interface is optional according to user needs;
5.Air circuit block alarm and self-protection function, the sampling pump is automatically turned off under the condition of gas path failure, effectively extending the service life of the sampling pump and the sensor;
6.Wide range of AC power supply, wider application range;
7.Built-in temperature and pressure automatic compensation module.
