*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.
***One side of transformer secondary is connected to signal common, so an Isolation transformer
or dedicated power supply may be required.
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
