Thermal Imaging

Thermal Imaging is effective at identifying building safety, sustainability, and performance issues.

All objects and surfaces with a temperature above absolute zero (minus 273C) emit thermal radiation. Thermal radiation is similar to visible light, but typically at infrared wavelengths that the eye cannot detect.

Infrared cameras convert thermal radiation into a visible light (thermal image) picture. Thermal imaging is a non-invasive, non-contact testing method that can be used to detect a broad range of building, mechanical and electrical issues before they become otherwise apparent. Thermal imaging is also used for a large and growing number of other applications including medicine, health screening, security, surveillance, agriculture and irrigation.

BENSS’ Thermographers are accredited by the ITC (Infrared Training Centre) in Sweden, and there are many examples where we can assist our clients with thermal imaging services.

Mechanical & Electrical Surveys


Mechanical or electrical breakdowns can lead to significant lost production time and repair costs, personal injury, or environmental damage.

BENSS provides thermal imaging of operational plant, equipment and machinery and can often detect a number of potential mechanical problems, including overheating bearings, impact zones, friction or uneven wear to drive belts, or leaking gaskets or seals.

Surveys of electrical boards and connections can detect components that are overheating or not functioning, or wiring defects and their location.
