The RHT-WM and RHT-DM transmitters have highly accurate and stable sensors for measuring relative humidity and temperature. The measured values are converted into 4 to 20 mA output signals that are linearly related to their readings.
Since they are microprocessor-based devices, it is possible to use the TxConfig-USB communication interface and the SigNow app or software, available for Android and Windows, to configure them. Outputs can be configured to transmit temperature, relative humidity or dew point. The RHT-WM model must be wall-mounted. The RHT-DM model has an extended sensor probe to be mounted in ducts or through walls.

When the integrity of a product or package is threatened because of variations in humidity, the control and recording of this variable are essential to avoid losses. To maintain the quality standard in measurements, equipment with calibration certification is required. Thus, NOVUS offers relative humidity calibration for all its compatible products and for third-party instruments.
