HMD60/70

Humidity and Temperature Transmitters for Ducts in HVAC Applications

 

The duct mounted Vaisala HUMICAP® Humidity and Temperature Transmitters HMD60 and HMD70 are designed for monitoring relative humidity and temperature in building energy management systems.
The combination of high accuracy, stability and reliable operation, make these products the ideal choice for demanding applications.

Resistant to chemicals and dust
The duct mount HMD60 and HMD70 transmitters can also be used in many industrial humidity monitoring applications, where their stability and resistance to chemicals and dust are of great value.
A useful feature of these duct mount transmitters is the ability to remove the electronics without removing the unit from the duct.
Measures both humidity and temperature
The HMD60 and HMD70 transmitters are available in three models: 

  • U for humidity measurement-only
  • Y for humidity and temperature measurement
  • T for temperature only

Fast, on-site cross checks
The accuracy of the transmitters is simple to check using either the Vaisala HUMICAP® Hand-Held Humidity and Temperature Meter HM70 or the Vaisala HUMICAP® Humidity Indicator HMI41.
