Definition of wiring terminals
Product features:
1、The instrument adopts a 7-inch touch screen display, which is easy to operate and displays clearly;
2、The instrument consists of a fixed oxygen content detection channel and two inspection detection channels. One instrument can complete the work of three single channel instruments.
3、The instrument is equipped with RS-232, RS485 communication ports, and an Ethernet interface that complies with the Modbus TCP protocol. Multiple communication ports enable users to easily access the Internet of Things;
4、The instrument can communicate one-way or two-way with the upper computer.
5、Original imported zirconia sensor with high measurement accuracy, fast response, and long service life;
6、Calibration is convenient and simple. It can be calibrated with air or standard gas at a single point, which can meet the precise measurement of oxygen content in the range of ppm~%;
7、Built in temperature and pressure monitoring modules and pipeline pressure sensors;
8、The instrument is equipped with an original imported suction pump, which works stably and has a long service life;
9、Equipped with gas path blockage alarm and self-protection function. After the air path is blocked, the air pump will automatically shut down, stopping the operation of the oxygen sensor, which can effectively extend the service life of the air pump and sensor;
10、Wide range AC power supply, with a wider range of applications;
