Electronic Humidity Alarms
Humidity Alarm

The electronic humidity alarm provides a local red light and a dry-contact closure when wet air is detected. The dry-contact alarm signal can be monitored at a remote location, wired to energize a horn or buzzer, and/or operate a shut-off solenoid valve to stop the flow of wet compressed air. The alarm operates on 115 volt AC power and is enclosed in a NEMA 4 rated box.
