Fluke 568

Fluke 568 – Overview

The Fluke 568 is a dual-mode thermometer that offers both non-contact infrared and K-type contact temperature measurement in one rugged unit. It features a graphical dot-matrix display, soft-key menu interface, and built-in data logging up to 99 data points. With adjustable emissivity, a high distance-to-spot ratio, and visual/audible alarms, it is ideal for demanding HVAC, industrial, electrical, and mechanical work.

Key Features

• Dual mode: Infrared measurement and K-type thermocouple contact measurement

• Wide IR range: −40 °C to 800 °C

• High distance-to-spot ratio of 50:1 for measuring small targets from safe distance

• Adjustable emissivity (0.10 to 1.00) and built-in material tables for improved accuracy

• Data storage of up to 99 readings with date/time stamps

• Hi/Lo visual and audible alarms for out-of-range values

• MIN / MAX / AVG / DIF functions for better analysis of temperature changes

• Laser sighting for targeting; two-level backlight for low-light conditions

• Bead thermocouple included, graphing display, USB interface for PC logging
