Highly accurate, stable humidity transducers designed for use with HVAC controllers such as the T7350 thermostat, H775 remote humidity controller, and W7760 DDC control. The ceramic technology humidity sensor is not affected by condensation and other limitations that sensors that use water soluble polymer coatings exhibit and provides excellent long-term stability.

• Ceramic Technology allows sensors to recover fully from condensation, fog, and high humidity. (H7655A uses a polymer capacitance humidity sensor)
• Will accept 20K? NTC temperature sensor (except H7655A)
• Highly accurate, repeatable, stable output with negligible hysteresis.
• Temperature compensated output.
• Zero and span trimmers, and increment/decrement recalibration feature.
• All units have selectable 4-20 mA, 0-10 Vdc, or 0-5 Vdc output.
• NIST traceable calibration; every sensor calibrated at 3 different points.
• All humidity sensors use the same enclosure as the T7770 sensor, except the H7655A, which uses the T7047-like enclosure.
