- WM291温湿度变送器
WM291 relative humidity transmitters include the interchangeable HYGROSMART module. The interchangeable module lets you recalibrate the transmitter simply by replacing the sensor head with the HYGROSMART module. As a result, maintenance costs are greatly reduced and machine down time is minimized.
Product Features
Humidity and temperature output signal: selectable through software
Digital output: RS485 (MODBUS)
