ModBusRTUOur so2 sensor uses electrochemical technology to measure SO2 concentration, and the reaction is rapid and sensitive. The transmitter is widely used in air quality testing and other occasions where SO2 and temperature and humidity testing are required. Using 485 communication, standard ModBus-RTU communication protocol, communication address and baud rate can be set, the farthest communication distance is 2000 meters. The equipment is 10-30V wide-voltage power supply, and the enclosure has a high degree of protection, which can adapt to various harsh conditions on site.
