International Safety Symbols - Extech Instruments IR270 User Manual

Introduction
Thank you for selecting the Extech IR270 IR Thermometer. The IR270 makes non‐contact
(infrared) surface temperature measurements and includes a laser pointer for convenient
targeting. The meter switches ON and starts scanning surface temperatures as soon as you pull
the trigger. This device is shipped fully tested and calibrated and, with proper use, will provide
years of reliable service. Please visit our website (www.extech.com) to check for the latest
