Humidity and Temperature Transmitters for Cleanrooms and Light Industrial Applications
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.
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.
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.
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 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.
