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.
