M330 Bed Bug-II


The IST Quadtek M330 Bed-Bug-II High-Temperature infrared Camera is a remote observation system which utilizes infrared camera electronics to monitor the smelt-bed in recovery boilers, monitor slag build up in utility power boilers and monitor product distribution and control, as well as burner efficiency in industrial process furnaces.

  • Infrared camera uses wavelengths that can penetrate fine particulate matter.
  • Dynamic range can view objects that are too cold or dim for visible light cameras.
  • Super-wide 110° diagonal field of view lens in several lengths..
  • Small front opening and improved seal reduces air usage and keeps lens cleaner.
  • Sapphire window, which is more durable and scratch resistant than other materials
