HU-225 – Furneco

MAMAC HU-225 WALL MOUNT HUMIDITY & TE MPERATURE TRANSMITTER | HVAC SENSOR

The HU-225 incorporates a sophisticated cross-linked bulk polymer capacitive sensing element that is immune to most contaminants and unaffected by condensation. For enhanced durability, the sensor is protected by a proprietary hydrophobic and oleophobic ePTFE filter. It provides a stable, repeatable output with negligible hysteresis and includes non-interacting zero and span trimmers for easy field calibration.

PRODUCT USES:

Commercial HVAC: Monitoring indoor space humidity in office buildings and schools.
Critical Environments: Precision control for cleanrooms, hospitals, and laboratories.
Specialized Storage: Humidity regulation in museums, data centers, and archive facilities.
Industrial Automation: Process control and ESD (anti-static) environmental monitoring.
