HT1O Series
Outdoor Humidity/Temperature

2% or 3% accuracy (NIST certification options)
0-5V/10V and 4-20mA RH/Temp (thermistors optional)
LCD display with field calibration menu
Field replaceable element

DESCRIPTION
The HO Series is designed to be mounted on the building exterior
to provide outside air RH measurement. The HO Series combines APPLICATIONS
excellent stability with reliable operation in 2% or 3% RH accuracy ▪ Outdoor humidity and temperature
options. Optional temperature transmitters, RTDs and thermistors measurement for building control
add further flexibilty when ordering. The standard LCD, gasketed lid
and field replaceable elements make the intitial installation and future
service a breeze.

FEATURES
Versatile

▪ 2% or 3% Rh versions with field replaceable sensor
▪ Switch selectable 5V/10V and 4-20mA RH/T transmitter Field replaceable element
outputs
▪ Thermistor/RTD output for temperature optional ▪ Ideal for harsh environments
