HT1D Series

Duct 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 APPLICATIONS
The HD Series is designed with both the engineer and field technician in ▪ HVAC room humidity and temperature
mind. The HD Series combines excellent stability with reliable operation in measurement and control
2% or 3% RH accuracy options. Optional temperature transmitters, RTDs ▪ Replaceable element is ideal for difficult
and thermistors add further flexibilty when ordering. The standard LCD environments such as swimming pools
and field replaceable elements make the intitial installation and future
service a breeze.
