Product Overview
This Fluke instrument is a combined contact and infrared thermometer. The Fluke 568 provides both non-contact IR measurement and contact measurement via a K-type thermocouple (mini-connector). The instrument's functions and measurement range are documented in the manufacturer's datasheet.
Key Features
- Infrared measurement range: -40 °C to 800 °C (-40 °F to 1472 °F)
- 50:1 distance-to-spot (D:S) ratio
- Infrared spectral response: 8 µm to 14 µm
- IR accuracy: ±1 % or ±1.0 °C (whichever is greater)
- IR response time: <500 ms
- Supports K-type thermocouple via standard mini-connector
- Data points: up to 99 stored measurements
- USB interface for data transfer

Typical Applications
The description and manufacturer's documentation specify concrete applications for the Fluke 568, including:
- Troubleshooting equipment using both contact and non-contact temperature measurements.
- Measuring smaller objects from a greater distance thanks to the 50:1 D:S ratio.
- Recording and subsequent analysis of up to 99 data points using built-in data logging and USB connection.
Technical Description
The Fluke 568 combines an infrared sensor with a Type-K contact input and offers adjustable emissivity including a built-in material table. The instrument's display is a dot-matrix with functional menus, and it has alarm functions (hi/low) as well as min/max/avg/dif functions. The unit can be powered by 2 AA batteries and use USB power when connected to a PC. Laser aiming is single-point with <1 mW output (classified as Class 2 in the 630–670 nm range).
