ModBusRTURS485 Nitrogen Dioxide(NO2) Transmitter
xiamen ZoneWu RS485 nitrogen dioxide(NO2) transmitter uses an imported large-brand electrochemical nitrogen dioxide sensor.
xiamen ZoneWu LoRaWAN Gas Sensor NO2 Sensor Features:
The reaction speed is especially fast, encountering changes in nitrogen dioxide concentration can react immediately, and is not afraid of external interference, and the stability is strong.
After our company's special compensation algorithm and gas calibration, the measured data is accurate and stable.
It is important to monitor nitrogen dioxide emissions in chemical production, power generation and automobile manufacturing plants.
The power supply voltage is not high, and a DC power supply of 10 to 30 volts can be used, making the supply convenient.
There are two output modes, RS485 and LoRa, which can be selected according to different needs.
The use of high-quality sensor elements ensures the overall performance of the equipment.
