HDI Mini Wall Mounted Remote Humidistat

The hygrostat type HG Mini is used as an on-off controller to control the relative air humidity on the DD Desiccant range. It can also be used to control air humidifiers and dehumidifiers in offices and computer rooms. Other areas of use are storage of foodstuffs and luxury foods, cooling rooms for fruit and vegetables, greenhouses for gardening use, the textile industry, the paper and printing industry, the film industry and hospitals.

The hygrostats can be used almost anywhere that air humidity has to be regulated or monitored. The room hygrostat HG Mini-i is designed so that the adjusting knob and the scale are inside the housing. This makes unauthorized manipulation by third parties more difficult.
