IR thermometers are essential tools in food safety, industry, and laboratories. But they only provide accurate readings when used properly.
How does an IR thermometer work?
IR thermometers detect infrared radiation emitted by a surface and calculate the temperature without contact – fast, safe, and hygienic.
Common application mistakes:
- Incorrect distance: Respect the distance-to-spot (D:S) ratio. The farther away, the larger the area measured.
- Wrong emissivity setting: Different materials emit heat differently. Adjust the emissivity on your device if possible!
- Reflections: Shiny surfaces can distort readings. Apply matte tape to create a reliable measuring point.
Practical tip:
Hold the thermometer perpendicular to the surface and avoid drafts or moisture fluctuations.
Applications:
- Food inspection (e.g. HACCP)
- Maintenance of machines and electrical systems
- Monitoring cooling chains or heating systems
