This humidity meter with alarm function and external sensor offers a large triple display for the simultaneous display of relative humidity, temperature and dew point. It is equipped with an integrated stand so that it can be conveniently placed on a desk or alternatively mounted on the wall using the bracket supplied. A visual and audible alarm signals when the humidity exceeds or falls below the set target value. The device also saves the maximum and minimum measured values. The external probe can be extended by up to 45 cm (18 inches), allowing measurements to be taken in hard-to-reach places, such as behind walls. The device is particularly suitable for humid environments where mold growth is a risk. The scope of delivery includes an integrated stand, a wall bracket and two AAA batteries.
