HI-2
Hygrostat, duct/wall mounting, external setting, 2-stage
Used in ventilation and air-conditioning ducts, climate chambers and dehumidification devices for controlling and / or monitoring air humidity in industry and agriculture. Not suitable for aggressive gases. Max. air speed 8 m / s, with sensor protection FS-HI 15 m / s. The hysteresis between the stages can be adjusted within the range 3…15 % r.H.. Mechanical range reduction possible using the setting pins located under the setpoint knob.
