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. 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. High Precision Humidity measurement with Vaisala HUMICAP® 180R humidity sensor comes with state-of-the-art precision, stability and environmental resistance. Temperature is measured with a highly accurate Pt1000 sensor element. Stability - Reliability The high quality and excellent stability of the measurements enables precise and reliable controls of HVAC systems, even in demanding conditions or sites. Traceable Accuracy The instruments are individually adjusted and delivered with a traceable (ISO 9001) calibration certificate. The humidity transmitter is easy to calibrate also on site using a Vaisala handheld meter or Vaisala Insight PC software.
