Fluke FLK-100-CLKT 4″ C-Range IR Window

Infrared checks become safer and smoother with the Fluke FLK-100-CLKT 4″ C-Range IR Window. Panels stay shut, tasks stay steady, and work carries on without long pauses or risky exposure. The window keeps its clarity in harsh weather, and it holds firm even when a site demands heavy use. This design helps teams keep inspection routines simple and repeatable, while the Fluke FLK-100-CLKT 4″ keeps visual quality stable.

Optic performance

Reliability matters during repeat scans, and the Fluke FLK-100-CLKT 4″ supports that aim through its tough crystal insert and consistent IR response. Each optic shields against moisture, dust and ultraviolet light, while the coating preserves a clear surface. Two sentences work together here to highlight that inspectors can keep gathering clean data without opening energised panels. Extra confidence comes from the way the optic keeps its shape and clarity across a wide temperature range, even during long inspection cycles.

Safety and application

Strong build quality gives the Fluke FLK-100-CLKT 4″ steady arc resistance and sound mechanical strength. Engineers can move through large sites faster because the access key and ID plate help with quick location checks. At the same time, its IP65 seal supports confident outdoor use, and its pull-out rating keeps the unit secure under strain. These traits allow safe routine work in active switchgear, where a stable window helps keep crews productive and protected.

Key Features
  • Designed for electrical IR inspections in energised panels
  • Coated optic helps reduce moisture impact during long use
  • Withstands demanding outdoor and indoor conditions
  • Supports visual, UV and wide-band IR inspection
  • Includes secure access key for controlled entry
  • Works with shortwave, midwave and longwave IR
  • Suitable for tough switchgear environments
  • Maintains clarity in very hot or very cold sites
  • Resists vibration and humidity during routine checks
  • Allows quick identification with supplied ID plate
