Maintenance technicians and experienced thermographers can quickly and easily detect troublesome hotspots with the user-friendly SKF Thermal Camera TKTI 21. With a thermal detector of 160 x 120 pixels and a visual camera, the TKTI 21 is suitable for many mechanical and electrical maintenance inspection applications. A wide temperature measurement range of –20 to +350 °C (–4 to +662 °F) makes the TKTI 21 suitable for many proactive maintenance programmes.

  • Visual and audible temperature limit alarm function alerts the user to abnormal conditions.
  • Automatic hot and cold spot cursors quickly pinpoints the extremes in a scene.
  • Up to five moveable temperature cursors/areas with individual emissivity settings for analysing complex scenes.
  • Temperature difference of two cursors can be displayed on screen enabling quick and easy temperature comparisons.
  • Isotherms, temperature gradients and area analysis boxes for advanced scene analysis.
  • Built-in emissivity tables allow easy emissivity value setting.
  • Eleven selectable colour pallets for ease of use.
  • Fully radiometric thermal and visual images are stored on the micro SD card provided.
  • Images can be voice annotated for later reviewing with the PC software.
  • Video output function allows the live image to be shown on an external display, useful when showing to a group of people.
  • Supplied with two standard camcorder batteries and an independent charger, enabling a long field usage time.
  • Rugged construction and, with an IP 54 rating, enabling use almost anywhere.
  • Comprehensive PC software suite for an unlimited number of users enables advanced image analysis and professional report writing.
