Fluke 572-2 High Temperature Infrared Thermometer

The Fluke 572-2 High Temperature Infrared Thermometer is a professional handheld temperature measurement instrument designed for high-temperature industrial environments. It provides non-contact infrared measurement up to 900 °C, allowing technicians to inspect hot surfaces without direct contact.

Its combination of long-distance targeting, adjustable emissivity, data storage and K-type thermocouple capability makes it suitable for routine inspection as well as troubleshooting in demanding industrial applications.

High-Temperature Non-Contact Measurement

The Fluke 572-2 measures infrared temperatures from -30 °C to 900 °C (-22 °F to 1652 °F). At temperatures of 0 °C and above, infrared accuracy is specified as ±1 °C or ±1% of the reading, whichever is greater, under the specified calibration conditions.

The 60:1 distance-to-spot ratio allows users to measure smaller targets from greater distances, which is particularly useful when equipment is hot, moving or difficult to access.

Dual Laser Targeting for Accurate Measurement

The 572-2 uses an offset dual laser sighting system to help identify the measurement area. The minimum spot size is 19 mm, while the 8 μm to 14 μm spectral response supports infrared temperature measurement across its specified range.

This makes the instrument suitable for inspecting individual components, pipes, process equipment, electrical connections and other localized heat sources.

Infrared and K-Type Thermocouple Measurement

In addition to infrared measurement, the Fluke 572-2 accepts K-type thermocouple input, allowing users to compare contact and non-contact temperature measurements.

The K-type thermocouple input supports a measurement range of -270 °C to 1372 °C, while the included bead probe is specified for -40 °C to 260 °C.
