Thermal Imaging Inspection

Infrared electrical inspections find hotspots caused by defects in connections and components. Infrared thermography is used to find areas of excess heat (caused by increased resistance) so that problems can be corrected before a component fails, causing damage to the component, creating safety hazards and productivity loss. Because increased heating is a sign of failure, infrared is the best diagnostic tool available for finding these hot connections in the early stages of degeneration. We provide PPM (Planned Prevention Maintenance) equipped with the latest technology in Thermal Electrical Inspection to ensure the best possible safety of your equipments.
