Humidity Alarm Sensor
● Adjustable relative humidity
● Change-over contact
● High switching capacity
● Easily accessible terminals
● Clip fixing
SAISEN003 is designed to activate the Red Flashing Alarm Light so that if relative humidity - (You set the device to an appropriate humidity level between 40% ~90%) exceeds the threshold the connected light will flash. 10 Ft. of cable connects the Humidistat and Light. The light uses "D" batteries. Call for A/C power light.
