Robust design for industrial measurements

The necessities of demanding professional use have been taken in careful consideration in the design of the instrument. The transmitters incorporate the renowned Vaisala HUMICAP® technology with humidity sensor HUMICAP® 180R. HMT120 and HMT130 are applicable for indoor and outdoor use alike, and the multi-purpose instrument fits in various applications and installation requirements.

HUMICAP® technology

The measurement probe of the instrument 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 sensor. Maintaining measurement traceability is easy as the probe can be exchanged with minimal downtime and process disturbance.

The transmitters are available as wall mounted or with a remote probe coming with a cable. The remote probe is ideal for rough conditions like high-temperature applications, or where space is limited. The devices can also be mounted outdoors using Vaisala installation kit and Vaisala Radiation Shield DTR502B.
