Infrared thermography is a technique that can measure surface temperature precisely without coming into contact with it. This is achieved by radiation detectors capable of measuring the energy emitted by objects in infrared wavelengths and converting it into temperature values. Corrections can be made by entering parameters into the camera for the emissivity of the environment and material, and for ambient temperature and distance to the object. Temperature values are usually based on a colour table.

The LIFTEC Fuel Cell Group owns a latest-generation FLIR A310 camera with a detector with 320x240 pixels, equipped with a 25° lens. The image frequency is 9 Hz, with a thermal sensitivity below 50 mK at 30°C, and an operating range of up to 350°C, with a reading precision of around ±2% and video recording. It can continuously monitor thermographic maps and collect data. It also has an alarm system that activates when it detects values above those set points.
