The Fluke 566 Thermal Gun is a versatile infrared and contact thermometer designed for both rapid surface temperature measurement and spot infrared detection. With rugged construction and dual-mode operation, this tool is ideal for HVAC technicians, maintenance engineers, and field service professionals working in building services, manufacturing plants, and industrial settings. It enables accurate surface contact readings along with non-contact infrared scanning, helping you identify hotspots, evaluate equipment condition, and ensure safe operational temperatures in one convenient instrument.
Key Features:
Dual mode: infrared non-contact measurement and surface contact probe for direct readings.
Rugged design suited for demanding field environments (maintenance, HVAC, etc.).
Fast response for spot checks and thermal scanning of equipment or surfaces.
Suitable for electrical, mechanical, and building system maintenance work.
Helps detect overheating, insulation failures, and equipment inefficiencies.
Compact and portable — ideal for technicians on the move.
