Frequently Asked Questions

Thermal imaging (also known as ‘Infrared Thermography’) uses heat-sensitive cameras to detect subtle differences in temperature. These cameras can detect temperature differences of less than 1ºC.

Originally designed for military use, thermal cameras are often seen used for search and rescue. Other applications include firefighters, who use the technology to see through smoke.

For non-contact measurement, thermal cameras can identify, capture and assess heat loss. This is used to inspect buildings, electrical equipment, rotating machinery and devices.

Thermal imaging is the only non-contact method of investigation for buildings – eliminating the need to physically inspect behind a finished structure.

Any object with a temperature above absolute zero (-273.15ºC) emits infrared radiation. The higher the temperature of the object, the greater the intensity of infrared radiation.

Infrared technology is designed to detect the intensity of radiation given off by an object. Once detected, a thermal camera creates an image of the object – based on the radiation it emits. This image is rendered using artificial colours, turning invisible radiation into a visible image.

Once captured, thermal images can be analysed to establish patterns and interruptions. For example, a loose connection in an electrical circuit or heat loss in a commercial building.

Thermal cameras cannot take accurate readings without adjustments. Factors such as reflectivity and emissivity must be changed to collect reliable information.

Accreditation verifies that a thermographer can:

  • Operate an infrared camera
  • Collect accurate temperature data
  • Create reliable thermal inspection reports

Our thermographers are accredited by both the British Institute of Non-Destructive Testing and the Awarding Body of the Built Environment. In addition to this, we have PCN Category 2 and 3 thermographers who are approved by the UKTA to conduct BREEAM surveys.

iRed is CHAS Accredited, Cyber Essentials Tier 1 Certified, CAA Approved and ISO 9001:2015 Certified.
