www.vaisala.com Vaisala HUMICAP® Humidity and Temperature Transmitters HMT120 and HMT130 Features/Benefits The HMT120/130 with and without a display. The Vaisala HUMICAP® 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. Performance The HMT120/130 incorporates Vaisala HUMICAP® technology that measures relative humidity accurately and reliably. The Vaisala HUMICAP® is resistant to dust and most chemicals. The 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, the cabling can be done through the back wall of the transmitter. Interchangeable Probe The HMT120/130 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 portable 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 remote probe. For high temperature applications or where space is limited, the remote ▪ Vaisala HUMICAP® technology with humidity sensor HUMICAP® 180R ▪ 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 ▪ Interchangeable probe (easy field calibration) ▪ ▪ Accurate and reliable ▪ ▪ Optional LCD display ▪ Wall-mounted or with a remote probe ▪ Constant output probe available ▪ Can be mounted outdoors using a Vaisala installation kit and the Vaisala Radiation Shield DTR504A ▪ ▪ Enclosure IP65 ▪ Suitable for cleanrooms and demanding HVAC and light industrial applications Resistant to dust and most chemicals USB cable available for a PC connection for maintenance 3-point NIST traceable calibration (certificate included) probe is ideal. The transmitters come with an optional LCD display, which shows the measurement results of selected parameters in selected units. The parameters are displayed simultaneously at two separate rows on the display.
