Infrared surface temperature sensor – IR 40 EL
The IR 40 EL active electrode is a special sensor that can be used to measure surface temperatures without contact.
As the electrode works on an infrared basis, it is ideal for measuring parts with a low heat capacity (e.g. wood, glass, insulating materials, etc.).
- Ideal sensor for detecting thermal bridges in buildings, for determining the dew point temperature, for measuring live, moving or vibrating parts and for determining the position of heating pipes or coils
- The position of the measuring spot can be displayed precisely using the integrated laser pointer
- The measuring spot diameter increases or decreases with changing distances from the object to be measured in a ratio of 6:1, i.e. at a distance of 250 mm from the object, the measuring spot has a diameter of approx. 46 mm. Directly in front of the sensor opening, the measuring spot has a size of 5 mm
- For measuring metallic or shiny surfaces, we recommend using the matt black IR 30/E 95 stickers, as otherwise incorrect measurements may occur
