PRODUCT DESCRIPTION
The DSMFX-2R series are multifunctional duct transmitters which measure
temperature, relative humidity and CO
2
concentration level. Based on the
temperature and relative humidity measurements, the dew-point temperature is
calculated. The series features a wide range of low voltage power supply and three
analogue / modulating outputs. All parameters are accessible via Modbus RTU.
