Thermal Imager

Step into thermal imaging

The Sonel KT-128 thermal imaging camera is a special camera.. Cost-effective, practical and handy, it is a powerful tool for everyday work. The camera is used for basic diagnostics. It is equipped with a matrix having a resolution of 120 x 90 pixels, supported by visual camera, laser pointer and additional features to fully meet the needs of users.


KT-128 is used always when the temperature of objects is important and may affect the operation of the equipment. Particularly useful in:

  • power engineering,
  • construction sector,
  • industry
  • HVAC.


  • measuring range -20°C…400°C
  • quick start
  • fast temperature measurement
  • automatic signalling of exceeded alarm threshold
  • saving IR images to SD card
  • built-in Li-Ion battery with 5-hour working time
  • interfaces: microUSB 2.0 type C, SD slot
  • can be set up on a tripod
