Fluke FLK-075-CLKT 3″ C-Range IR Window

A strong build gives the Fluke FLK-075-CLKT 3″ safe use during infrared work on live panels. It keeps image quality high and cuts time spent on each check. It also limits exposure to risk because the window stays fixed while the inspection takes place. This steady approach supports routine tasks in busy electrical rooms.

High Strength and Clear Optics

A sealed CLIRVU crystal sits at the core of the Fluke FLK-075-CLKT 3″. It holds its shape under intense heat and pressure during an arc-fault event. It stays stable in harsh sites, and it does not degrade when it meets moisture or vibration. It also keeps clarity over long periods, which helps teams produce repeatable readings.

Certified for Harsh Environments

Outdoor and indoor tasks work well with the Fluke FLK-075-CLKT 3″. Its IP65 and Type 3/12 ratings support long-term field use. Each unit also helps with visual, UV and thermal methods, which lets teams spot faults early and act fast. This broad support makes inspections smoother and gives maintenance teams more confidence during planned checks.

A Kwik Twist cover supports quick access during checks and holds in place with a simple twist. The Fluke FLK-075-CLKT 3″ arrives ready with an ID plate, a key, a template and clear guidance, which speeds up fitting and reduces downtime. This leads to safer, faster and more repeatable inspection work across complex sites, and it also reduces the need for multiple technicians during routine checks.

Key Features
  • Uses a sealed CLIRVU crystal for clear IR images
  • Handles arc-fault pressure up to high levels
  • Works with UV, visual and thermal modes
  • Supports IR-Fusion use with Fluke cameras
  • Kwik Twist cover allows quick access during checks
  • Supplied with an ID plate for simple site tracking
  • Resists moisture, acids, alkalis and vibration
  • Stays stable in outdoor Type 3/12 conditions
  • Helps meet NFPA 70E safety steps during inspections
  • Cuts inspection time by allowing closed-panel testing
  • Keeps viewing area clear at 68 mm diameter
