GED20 Nitrogen Dioxide Sensor for Mine

The GED20 nitrogen dioxide sensor for mines is used to monitor the concentration of nitrogen dioxide in general industrial environments. With a single-chip microcomputer, the sensor circuit supports the output of standard signals. It is capable of continuously and automatically converting the nitrogen dioxide concentration into standard electrical signals and transmitting them to the associated equipment. It has the functions of local display of nitrogen dioxide concentration, over-limit sound and light alarm, etc. The power supply circuit of the sensor is a switching power supply, to reduce the overall power consumption, which is beneficial to increase the transmission distance.
