Honeywell Humidity Transmitter Integral Duct Probe H7625B2006 Features: Ceramic Technology overcomes the limitations of other resistance based humidity sensors that use water soluble polymer coatings. Ceramic Technology allows sensors to recover fully from condensation, fog, and high humidity. 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 2, 3, and 5 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.
