This document introduces the Fluke 572 Precision Infrared Thermometer, which is used for non-contact temperature measurement. The thermometer determines the surface temperature of objects by measuring the infrared energy radiated from the surface.
The Fluke 572 is a non‑contact infrared thermometer designed for quick surface temperature measurements. It uses the infrared energy emitted by an object to calculate its temperature without physical contact.
This manual covers safety warnings, laser precautions, device functions, measurement methods, installation, fault diagnosis, technical specifications, and warranty details, helping users operate and maintain the instrument safely and accurately. This manual is written in Chinese.
