ATF 2
Exterior/damp area temperature sensor, with passive output
Application
The ATF 2 is an exterior temperature sensor with IP65 housing with quickrelease screws and an external stainless steel sensor tube. For recording the exterior temperature as well as in damp areas. It is used as weather sensors for mounting on exterior walls, in cold stores and greenhouses, in halls, in the industrial sector and in agriculture. Exterior areas, installation is preferably on the north side or in a protected location. In direct sunlight, use the sunshade.
