HUMICAPâ Humidity and Temperature Transmitters HMT120 and HMT130 Features • Accurate and reliable measurement with Vaisala HUMICAPâ humidity sensor technology • Interchangeable probe (easy field calibration) • Resistant to dust and most chemicals • Enclosure IP65 • Traceable calibration certificate: 3 points for humidity, 1 point for temperature • Temperature-only models TMT120 and TMT130 also available • Suitable for cleanrooms and demanding HVAC and light industrial applications Vaisala HUMICAPâ Humidity and Temperature Transmitters HMT120 and HMT130 are designed for humidity and temperature monitoring in cleanrooms and are also suitable for demanding HVAC and light industrial applications. Options • Humidity parameter options: relative humidity, dew point/frost point, wet bulb temperature, enthalpy, absolute humidity, mixing ratio, vapor pressure, and saturation vapor pressure • 2-wire loop-powered or 3-wire voltage output configurations • Optional LCD display • USB cable available for a PC connection for maintenance • Wall-mounted or with a remote probe Performance The HMT120 and HMT130 transmitters incorporate Vaisala HUMICAPâ humidity sensor technology that measures relative humidity accurately and reliably. Vaisala HUMICAPâ sensors are resistant to dust and most chemicals. The HMT120 and HMT130 transmitter enclosure is optimized for use in cleanrooms. The smooth surface of the enclosure makes it easy to clean and the enclosure material is chosen to tolerate purifying agents. Furthermore, cabling can be done through the back wall of the transmitter. • Constant output probe available Interchangeable probe • Can be mounted outdoors using a Vaisala installation kit and Vaisala Radiation Shield DTR504A The HMT120 and HMT130 transmitters use a fully interchangeable relative humidity probe. The probe can be easily removed and replaced with a new one without having to adjust the transmitter, which allows for easy and quick recalibration of the transmitter. The probe can be adjusted using one of Vaisala's handheld meters as a reference. Also available is a constant output probe with fixed RH and T output for convenient inspection of the monitoring system and signal transfer line. Available options The HMT120 and HMT130 transmitters are available as wall mounted or with a remote probe. For high temperature applications or where space is limited, the remote probe is ideal. The optional LCD display shows the measurement results of selected parameters in selected units. The parameters are displayed simultaneously on two
