Infrared Thermometers

Temperature guns are best for taking surface measurements where users need to maintain a distance from the temperature source.

The non-contact nature of infrared laser thermometers enables users to safely measure surfaces with extreme temperatures, such as hot plates and pizza ovens. IR temperature thermometers are also ideal for taking temperatures of hard-to-reach areas like pipes.

Medical-grade non-contact thermometers are ideal for measuring body temperatures, allowing users to distance themselves from individuals with fever symptoms without needing to frequently sanitise. 

ETI’s infrared thermometers cater to various industries, including industrial, HVAC, medical, and food applications.

Infrared thermometers measure surface temperature by detecting infrared radiation emitted by an object. They provide quick, non-contact readings, making them ideal for high-heat or hard-to-reach areas.

Yes, high-quality infrared thermometers provide precise readings when used correctly. Ensure you’re measuring the right surface at the correct distance and adjusting for emissivity if needed.

Infrared thermometers are not suitable for measuring internal temperatures (like food or liquids) and may give inaccurate readings on reflective or shiny surfaces unless the emissivity setting is adjusted. They also cannot measure through transparent surfaces, such as plastic packaging or glass.

 

Emissivity measures how well a material emits infrared energy, and the setting on your thermometer should match the material you're measuring. Most IR thermometers have a default emissivity of 0.95 since most materials are close to this, but many allow adjustments for greater accuracy on different surfaces.

See the Emmisivity table here.

Yes, but only medical-grade infrared thermometers should be used for this purpose. Standard IR thermometers may not provide accurate body temperature readings.

This depends on the distance-to-spot (D:S) ratio of your thermometer. An 8:1 ratio means that from 8 metres away, the measurement spot is 1 metre wide, while a 50:1 ratio means the spot is just 1 metre wide even from 50 metres away. Always check your product guidelines for the best results.
