The dew point switch 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.
