  • Overview
  • Series Specifications
HP 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.

*Reset Rate is the time required to recover the 50% RH after exposure to 90%RH for 24 hours.**Specified accuracy with 24VDC supplied power with rising humidity. RTD/Thermistors are not compensated for internal heating of product. 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.
