Description

High quality dew point switch that sends early-warning signal before dew point is reached which can be used to control condensation in critical environments.

This is achieved by a quick and accurate response in monitoring relative humidity in combination with temperature.

Status LED light indicates condensation warning as 90% threshold is reached, as well as potential electronic failure with the device.

The sturdy housing is well ventilated, coupled with a thermally conductive aluminum alloy contact surface contact making it suitable for a variety of applications.

This product is designed for mounting directly on a pipe with a flexible strap included, or to a directly to a flat surface via the screw mounting holes.
