Infrared Thermometers

An infrared thermometer infers temperature by measuring the thermal radiation that an object emits. This means that temperatures can be measured at a distance, without having to be in direct contact with the object. This is not only ideal for measuring the temperature of difficult to reach areas, but also means that accurate measurements can be taken of moving parts, or of objects in controlled atmospheres.

The RS Components range of infrared thermometers features high quality models from leading brands such as Fluke and Testo.

How Does an IR Thermometer Work?

Infrared thermometers have a lens that focuses infrared radiation onto a detector which converts it into a readable electronic signal. Because of this, it is possible for nearby objects emitting their own thermal radiation to interfere with the measurement- even the thermal body temperature emitted by the user.

Most non-contact thermometers are able to be calibrated to mitigate interference and customise the device to the application at hand. With adjustable temperature ranges and distance-to-spot ratios, an IR thermometers is a versatile and easy-to-use temperature measurement solution.

Handheld infrared thermometers have a laser for aiming purposes, so you can be sure your non-contact measurement is area accurate.

What Type of IR Thermometer Do I Need?

Non-contact infrared thermometers are typically robust and versatile, with LCD screens that can display either easily discernible numerical values, or more advanced real time heat map overlays. As models have different capabilities when it comes to accuracy and maximum temperatures measured, it is easy to select a IR thermometer that best suits your requirements and budget.

Pocket-size models are available for added convenience, and ATEX models are available for use in hazardous environments.
