HD Deluxe Duct and Outdoor Humidity Sensors

Deluxe Duct and Outdoor Humidity Sensors
HD

HD/HO Deluxe humidity transmitters provide an ideal solution for measuring relative humidity in all conditions. All devices are equipped with a thin-film capacitive sensor that is easily replaceable in the field. These sensors are calibrated to NIST standards, with certificates available. The duct mounted HD is encased in a die cast metal housing for extra strength. The outdoor HO housing is completely weather proof – the most rugged sensor available. All Deluxe models come with an extended five-year warranty.

Sense humidity in harsh environments
• Thin-film polymer capacitive sensor element recovers from 100% saturation
• Fully interchangeable element to 1% (HD only), 2%, 3%, or 5% accuracy. Calibration-free!
• Replace element in the field...maintain accuracy and minimize downtime Rugged industrial design
• Duct sensor element can be serviced without disturbing conduit
• Polarity insensitive, two-wire 4-20mA, or 3-wire 0-5/0-10VDC versions...flexible systems compatibity Calibration-free interchangeable NIST traceable HS element
• HS element is microprocessor profiled with onboard nonvolatile memory
• Multi-point digital calibration to NIST standards
• NIST certification available
• Minimizes field calibration downtime
