The RS485 chlorine gas transmitter designed by our company has the characteristics of fast response, high sensitivity, and strong anti-interference ability. Equipped with high-performance chlorine gas sensors and microprocessors, it has the characteristics of high detection accuracy, stable performance, and low power consumption. Suitable for chlorine gas concentration monitoring in industrial safety, environmental monitoring, industrial production and other places. This device adopts a wide voltage 50-28V DC power supply, 485 signal output, standard ModBus RTU communication protocol, can set ModBus address, can change baud rate, and has a communication distance of up to 2000 meters.

This industrial wall-mounted temperature and humidity transmitter features a clear LCD display and high-precision sensing. Equipped with RS485 output and standard Modbus RTU protocol, it easily integrates into building automation, HVAC, cleanrooms, warehouses, and environmental monitoring systems. The probe supports a wide operating range of -40℃ to +120℃, while the transmitter circuit works reliably from -20℃ to +60℃ (0~95%RH non-condensing). With ±0.4℃ temperature accuracy and ±2%RH humidity accuracy (B accuracy: ±0.5℃ / ±3%RH), it delivers stable, real-time data. Powered by 10-30V DC, the device supports both wall-mounted and DIN-rail installation. Optional analog outputs (4-20mA / 0-10V) are available. The LCD screen displays temperature, humidity, and device address, and parameters can be adjusted via onboard buttons. Built for industrial environments, it ensures long-term reliability and easy maintenance.
