VERSATILE FAMILY OF TRANSMITTERS

The HMP 140 series includes the wall-mounted HMP

141, the HMP 142 for installation in ducts or chan-

nels and the HMP 143, which has a sensor head that

can be installed directly in the process environment

being measured. The HMP 143's cable can be

extended by the user to a total of 100 meters in

length.

A novel feature of the 140 series duct unit is the

ability to remove the electronics without disassem-

bling the unit from the duct.

HIGH PERFORMANCE SENSOR

The 140 series feature Vaisala's HUMICAP® humid-

ity sensor, known for its accuracy, reliability, and

long-term stability. Resistant to dust and most

chemicals, the HUMICAP

is a great asset in indus-

trial environments especially where there is risk of

dew or particulate contamination.

QUICK ON-SITE CALIBRATION

These transmitters can be calibrated easily in

minutes without disturbing operation, using Vaisala's

portable calibrators. If using saturated salt solutions,

the electronics of the transmitters can be discon-

nected easily without disconnecting the cable.
