IR-ESC Series Scanning Type Radiation thermometers

The IR-ESC series is scanning type radiation thermometers for low temperature and is applicable to measure width-direction temperature patterns of moving or rotating objects. The temperature range is 100°C to 600°C.
The system is consisted of a scanning unit, a display/operation unit with a built-in exclusive software for operation and graphic display, and connection cables.


  • The small sized (300 x 200 x 120mm) scanning unit is easy to install.
  • The temperature range is wide (100°C to 600°C).
  • The display/operation unit with a built-in exclusive software displays thermal-images in pattern, trend and color modes (Windows95 or WindowsNT4.0, to be specified).
  • The output is 0 to 5VDC for 7 position points + 1 peak point or 3 zone peak points.
  • For targeting of objects, a direct viewfinder type or laser spotting type are available. (option)
  • An exclusive kiln shell software for cement kilns is separately prepared.
