Standard Duct Humidity Sensor, 2% Accuracy, 4 - 20 mA Output

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. 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.

Applications:

• Controlling HVAC systems for improved comfort and energy savings
• Museums, schools, printing shops, and other locations requiring humidity control
• Facilitating compliance with ASHRAE standards for environmental control and indoor air quality
