Technical Advice for Infrared Temperature Measurement

 

Emissivity: What It Is and Why It Matters

What is emissivity? This is what you need to know about the surface you are measuring, to help you choose the right sensor and achieve an accurate temperature reading.


Understanding and Using Infrared Temperature Sensors

A technical introduction to infrared thermometry.


Reflected Energy Compensation

If the infrared temperature sensor is positioned outside a hot chamber such as an oven or furnace, and aimed at an object inside the chamber, the reflection of the hot interior of the chamber on the object surface can influence the measurement. Reflected Energy Compensation is used in this case to ensure an accurate reading. Find out more with this guide.
