Fluke HWK-075-CLKT IR Window, For Use With C Series

This multi-function tester accessory is an infrared inspection window designed to permit thermal and Visual assessment of live electrical panels without removing doors. It provides a sealed optical access point for industrial and commercial switchgear, enabling faster, safer inspections in indoor and outdoor settings while maintaining panel integrity and environmental protection.

• Withstands 50kA arc energy for 30 cycles providing high arc-resistance
• ClirVu coating prevents moisture degradation in extreme temperatures
• Viewing aperture area 3632 mm² allowing clear thermal scene capture
• Optic thickness 2mm ensuring robust transmissive strength
• IP65 enclosure rating offering dust-tight and water-spray protection
• Supplied with security key and drilling template reducing installation time

• Suitable for electrical infrared inspections on distribution panels
• Ideal for industrial thermal imaging window installation on switchgear
• Used for routine safety checks in automation and electronics facilities
• Can be used for on-site condition monitoring in mechanical plants
• Used with C Series tester accessory configurations for efficient testing

The accessory endures cyclic humidity and vibration test regimes and resists insulating-material degradation up to 100 °C, supporting use in challenging ambient conditions.

It allows inspectors to perform thermal and UV-capable imaging through the panel, eliminating door removal and enabling quicker fault localisation and reduced downtime.

It has been subjected to multiple arc-testing protocols including ANSI C37.20.7 50kA for 30 cycles and IEC 62271 assessments reflecting compatibility with high-energy fault scenarios.

The unit includes an attached identification plate for site numbering, a security access key and a self-adhesive drilling template to Streamline installation.
