DESCRIPTION
HN and HP Series probe type humidity transmitters are easy to install and
exceptionally accurate. Their long-term stability and trouble-free serviceability
make them the best in the industry. The electronics are embedded inside the probe,
protecting them from condensation-related failures. The thin-film capacitive HS
sensor elements are factory calibrated using NIST traceable calibration equipment,
eliminating the need for field calibration. Field replacement of the sensor element is
a snap with the patented removable sensor, lowering costs and reducing downtime.
APPLICATIONS
●
HVAC control for improved comfort & energy savings
●
Museums, schools, printing shops, and other locations requiring
humidity control
●
Facilitating compliance with ASHRAE standards for environmental control
and indoor air quality

† The HS sensing element has a 1-year warranty. The element is not a part of the 5-year product warranty.
* One side of transformer secondary is connected to signal common, so an Isolation transformer or dedicated power supply may be required.
** Specified accuracy with 24VDC supplied power with rising humidity. RTD/Thermistors are not compensated for internal heating of product.
*** Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24 hours.
Shielded cabling is required for conformance to EMC standards. Technical information is available from factory upon request or is available on our website: www.veris.com.
