HD1NVSTK | RH Duct | 1% | NIST | 5/10VDC | Temp | 10k w/11kS | Veris

HD series deluxe humidity transmitters provide an ideal solution for measuring relative humidity in a wide range of 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. All deluxe HD models come with a standard 5 years warranty.

• Sensor element - thin-film capacitive sensor element recovers from 100% saturation
• Accuracy - fully interchangeable element to 1% accuracy no calibration
• Field replaceable - replace element in the field maintain accuracy and minimize downtime
• Easy servicing - duct sensor element can be serviced without disturbing conduit
• Potted circuitry - prevents costly condensate shorts
• Flexibility - polarity insensitive, 3-wire 0 to 5/0 to 10 VDC versions flexible systems compatibility save time in the field, stock fewer devices
• RH duct enclosure
• 1% NIST
• 3-wire, observe polarity
• Digitally profiled thin-film capacitive (32-bit mathematics) US Patent 5,844,138 HS element, this sensing element has a 1 year warranty
