Dwyer Instruments RHP-W Series transmitters utilise advanced sensors to measure relative humidity, temperature and dew point and display results on an LCD within 15 seconds. They are ideal for HVAC systems, laboratories, data centres, manufacturing facilities and similar settings. These units have a fully vented polycarbonate housing to provide ample airflow across the sensor and help improve measurement accuracy. They come equipped with internal dip switches to customise the settings of the transmitters, including various parameters, output scaling, calibration offsets and more. These transmitters use an RTD (or thermistor) and capacitive polymer sensors to measure temperature, humidity and dew point range. They are mounted on walls or flat surfaces with the help of mounting brackets and provide a secure connection.
