Fluke 566-2 Thermal Gun Infrared & Contact Thermometer
The Fluke 566-2 is a rugged two-in-one thermometer that combines infrared (IR) and contact (K-type thermocouple) measurement capabilities. With a 30:1 distance-to-spot ratio, it is ideal for industrial, electrical, and mechanical diagnostics, providing precise temperature readings from -40°C to 650°C (-40°F to 1202°F). The device features adjustable emissivity, a dot-matrix display, data storage, and both visual and audible alarms for added convenience and accuracy.
Description
The Fluke 566-2 is an advanced two-in-one infrared and contact thermometer, perfect for professionals working in industrial, electrical, HVAC, and mechanical environments. This versatile tool allows for both non-contact temperature measurements using infrared technology and contact temperature measurements through K-type thermocouples, making it a highly flexible solution for a wide range of applications.
With a 30:1 distance-to-spot ratio, the Fluke 566-2 can measure smaller objects from a greater distance, making it safer and easier to take temperature readings without having to physically access the equipment. The device features a broad temperature range of -40°C to 650°C (-40°F to 1202°F) for infrared measurements and -270°C to 1372°C (-454°F to 2501°F) for K-type thermocouple contact measurements, ensuring it can handle even the most demanding industrial tasks.
The Fluke 566-2 is designed for ease of use with an intuitive dot-matrix graphical display and soft-key menus, allowing users to quickly adjust settings like emissivity and access advanced functions. Audible and visual alarms notify users when measurements fall outside pre-set limits, and the device can store up to 20 data points with a date/time stamp for easy tracking and documentation. The thermometer’s adjustable emissivity allows for accurate temperature readings across various materials, ensuring precise diagnostics.
Its rugged, ergonomic design ensures that the Fluke 566-2 can withstand harsh working environments, making it ideal for those who require durability and reliability in tough conditions. Whether you are troubleshooting electrical panels, HVAC systems, or mechanical equipment, the Fluke 566-2 provides the flexibility and accuracy you need for reliable temperature diagnostics.
