Every Degree Matters™
Your practical guide to non-contact temperature measurement — how infrared thermometers work, when to use them, and how to avoid costly measurement errors.
Infrared101.com focuses exclusively on infrared temperature measurement using handheld infrared thermometers. We are not a neutral lab — we are TIP TEMPerature Products, and we believe that educated customers make better purchasing decisions, experience fewer measurement errors, and get more value from their instruments. This site is our straight-talk guide to IR thermometry: how it works, when to use it, and how to avoid the most common mistakes.
An infrared thermometer is a non-contact temperature measurement instrument that detects the infrared energy emitted by a surface and converts it into a temperature reading. Unlike contact probes, IR thermometers measure instantly from a distance — making them ideal for moving targets, hazardous environments, and rapid scanning applications.
Every object above absolute zero emits infrared radiation. The amount emitted depends on the object's temperature and its emissivity — the efficiency with which a surface emits that energy. Understanding these two factors is the foundation of accurate infrared measurement.
Navigate through our practical guide to master infrared temperature measurement.
Understand the physics of infrared radiation, how IR thermometers detect surface temperature without contact, and what the sensor is actually measuring.

Specialty Applications
Our product line covers the majority of handheld infrared applications — but some projects require a more specialized solution. If your application involves high-temperature furnaces, thermal imaging, OEM integration, or custom calibration, we'd like to help you find the right partner rather than the wrong product.
