Fluke HWK-075-CLKT Electrical Tester, Accessory Type IR Window, For Use With C Series

The Fluke FLK-075-CLKT is an infrared (IR) window designed to make thermal inspections on live electrical switchgear safe and efficient. Rather than removing panel covers, which risks arc-flash or exposure, this IR window lets maintenance technicians inspect energised equipment without opening enclosures. It transforms any compatible switchgear panel into a safe viewing port for infrared, visual, and fusion imaging.

Advanced Features and Benefits of Buying the Fluke IR Window for C Series

• Provides a clear viewing area (≈ 3632 mm²) for thermal or visual inspection.
• Tested and rated for heavy-duty safety compliance.
• Enables use with thermal imagers, visual cameras or fusion-enabled inspection tools.
• Suited for both indoor switchgear and outdoor distribution panels under harsh environmental conditions.
• Built-in security key cover, identification plate and installation template simplify installation and help ensure proper usage and traceability.

Why is it a Smart Choice for Maintenance & Safety Teams?

Using the FLK-075-CLKT saves significant time and reduces risk. Because inspections can be done without removing doors, outages or shutdowns become less necessary, helping keep uptime high. The arc-flash rating protects inspectors from high-energy electrical faults, improving safety. The wide field of view and multispectral capability give absolute confidence that thermal anomalies, loose connections, or overload spots can be quickly spotted with an infrared camera or during a visual inspection before they worsen. Long-term, this helps reduce unplanned downtime, support preventive maintenance and improve reliability of electrical infrastructure.

Typical Uses in Industry & Facilities

• Thermal inspection of live switchgear, distribution boards, or motor-control centres.
• Periodic preventive maintenance surveys in commercial or institutional facilities.
• Monitoring and condition-based maintenance of outdoor or indoor electrical panels.
• Routine inspections using thermal imaging for early detection of hot spots, loose connections or overload conditions in distribution systems.
• Applications in manufacturing, utilities, infrastructure, or any facility.
