The Therma-Hygrometer simultaneously displays humidity, temperature and a colour coded comfort level. The minimum and maximum readings are also recorded and can be displayed or reset with the push of a button.

The unit is ideal for monitoring both temperature and humidity in classrooms, offices, factories and similar to ensure optimum working and learning conditions are maintained. The ABS case, measuring 20 x 100 x 110 mm, incorporates a useful foldaway stand and a keyhole slot for hanging on a wall.
