Description

The humidity and temperature transmitters Vaisala HUMICAP® HMW90 series for wall, measure relative humidity and temperature in indoor areas requiring a high level of accuracy, stability and reliability.

Very flexible, the HMW90 series offers a wide range of options and features. The display is protected by a sliding cover is blind or has a viewing window. Output options include special scales and calculated the following parameters: dew point, mixing ratio, enthalpy, wet bulb temperature, dew point depression and absolute humidity.

Ease and speed of installation
The HMW90 transmitters are quick and easy to install. The wiring is done by the back, which makes it easy to set up electronics and sensors after completing wiring. Access to configuration switches requires opening the housing. In standard models, the most common settings such units metric / non-metric, humidity settings / dewpoint and relay set point can be easily changed without special tools.

A wide range of calibration options
Calibration and adjustment on the site is exceptionally simple. The cover slides to reveal correction potentiometers for the one-point calibration of humidity and temperature settings without disturbing the measurement. The integrated display makes it clear and convenient adjustment instantly showing the effect of changes. Service connector allows two-point calibration with either a PC or with the portable instrument for measuring humidity and temperature HUMICAP® HM70.

The HMW90 transmitters incorporate a measurement module user replaceable and can be ordered as a spare part. This module comes with a calibration certificate. Calibration services are available at Vaisala service centers.

The cover slides to discover the correction potentiometers and service connector for recalibration.
