Plant and building inspectors can quickly and easily detect troublesome hot and cold spots with the user-friendly SKF Thermal Camera TKTI 31. Equipped with a high-resolution thermal detector of 380 x 280 pixels and a visual camera, the TKTI 31 caters to a wide range of applications. A high thermal sensitivity of just 0.06 °C allows small temperature differences to be clearly displayed.

  • A wide temperature measurement range of –20 to +600 °C (212 to 1 112 °F) makes the TKTI 31 suitable for many proactive maintenance programmes and high temperature applications.
  • High thermal sensitivity enables applications, such as air ingress and building moisture, to be easily visualised where small temperature variations matter.
  • 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 for easy emissivity value setting.
  • Eleven selectable colour pallets for ease of use.
  • 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.
  • Fully radiometric thermal and visual images are stored on the micro SD card provided.
  • Supplied with two standard camcorder batteries and with an independent charger, allowing for long field usage.
  • 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.
