THERMASGARD
Calibratable room temperature measuring transducer THERMASGARD
con tinuous output, with or without optional display for displaying the actual temperature in an
elegant enclosure made of plastic, with snap-on lid, base with 4-hole attachment for installation
on vertically or horizontally installed in-wall flush boxes, with predetermined breaking point for
on-wall cable entry, or in enclosure made of stainless steel (top and bottom part are of stainless
steel, the lid is screwed on), vandal-proof version e.g. for schools, military barracks, and public
buildings. This room temperature transmitter ⁄ residential room temperature sensor is used to
detect ⁄ display temperatures in closed dry rooms, in apartments, in offices, supermarkets and
business facilities.
