Infrared Food Safety Thermometers: Uses and Limits

Infrared thermometers speed up surface screening without touching food. They cannot read a food's core, so confirm critical internal temperatures with a clean penetration probe.

An infrared food safety thermometer reads thermal radiation from a surface without contact. It is useful for quickly screening delivered food, chilled displays, hot-holding pans and griddles, then identifying items that need a probe check.

Best Infrared Meat Thermometers for Cooking in the UK

ThermoWorks Thermapen IR is the strongest all-rounder because it combines a surface scanner with a penetration probe. INKBIRD IHT-1M is another two-in-one option; Etekcity models suit surface-only checks.

Common questions

Questions before you buy

Can infrared thermometers be used for food safety?

Yes, for rapid surface screening. Confirm any critical internal temperature with a clean penetration probe.

Can an infrared thermometer see through food packaging?

No. It reads the package surface, not the food beneath it. Follow an approved between-pack or probe method where required.

Why does shiny metal give an odd infrared reading?

Low-emissivity reflective surfaces can reflect surrounding infrared energy. Use the maker's emissivity guidance or measure a suitable non-reflective area.

How close should an infrared food thermometer be?

Use the stated distance-to-spot ratio so the target completely fills the measured area. Farther away means a larger sampled spot.
