The SHURE GM320 Infrared Thermometer is a versatile, easy-to-use non-contact temperature measurement tool designed for industrial, commercial, and household applications. Whether you’re checking motor temperatures on a factory floor, verifying cooking surface heat in a professional kitchen, diagnosing electrical panel hotspots, or troubleshooting HVAC systems — the GM320 delivers instant, accurate readings without ever touching the surface being measured.

With its ergonomic pistol-grip design, large backlit LCD display, and intuitive one-trigger operation, the GM320 is built for fast, repeated use in demanding environments. It’s compact, lightweight, and powered by standard AAA batteries — ready to work right out of the box.

⚠️ Important: The GM320 is an industrial surface thermometer and is not designed or calibrated for human body temperature measurement. Do not use it for medical or fever-detection purposes.

How It Works

The GM320 uses infrared (IR) sensing technology to detect the thermal radiation emitted by any surface without physical contact. Simply:

1. Point the device at the target surface
2. Pull and hold the trigger
3. Read the temperature on the LCD display in 0.5 seconds

The built-in laser pointer helps you aim accurately at the exact spot you want to measure, while the backlit LCD ensures clear readings even in dim work environments.

Key Features
