PRODUCT DESCRIPTION
The RSMFX-2R series are multifunctional room transmitters which measure
temperature, relative humidity, CO
2
concentration level and ambient light.
They feature a wide range of low voltage power supply and three analogue/
modulating outputs. All parameters are accessible via Modbus RTU.
