Thermography interests
• To save on the invoices of electricity by
improving the output of the electric installations
• To locate the energy losses
• To avoid the stops of production, machine
breakings
• To eliminate the fire hazards
• To decrease the insurance premium

Why thermography is it so useful ?
3 essential advantages:
•Non-contact measurement
•Method with two dimensions
•Real time method

Why use thermography?
•Better safe than sorry
That should be our motto!
•Infrared thermography: a powerful diagnostic
tool for preventive maintenance
Enables corrective action to be taken prior
to costly breakdowns
