Standard Wall
Humidity Sensors
DESCRIPTION
HEW Standard Series wall mount humidity transmitters offer high performance in an
easy to install housing at an affordable price. The thin-film capacitive sensor element
provides high accuracy and performance, great long-term stability, and full recovery
from saturation. Temperature sensing options are also available.
The wall housing was created using sophisticated thermal analysis techniques for
optimum airflow. It is ideal for schools and other applications requiring exceptional
durability and a discrete appearance. All Standard models come with a standard
one-year warranty.
APPLICATIONS
● HVAC economizer control
● Managing energy systems
● Facilitating ASHRAE standards for environmental control
