HMD60/70 Humidity and Temperature

Transmitters for Ducts in HVAC Applications

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, and T for temperature

only.

Fast, On-Site Calibration

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. The

calibration can be done in seconds

with a single potentiometer without

disturbing the operation, resulting

in great savings both in maintenance

time and costs.

Vaisala HUMICAP

Humidity and Temperature Transmitters HMD60 and HMD70 are

designed for use in air conditioning applications where accurate and stable control

of relative humidity and temperature are required.

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.
