Infrared Thermography is one of the essential devices for the predictive maintenance routine. Thermal imaging technology has developed into one of the vital and useful diagnostic instruments for industrial applications. By detecting anomalies which are invisible to the naked eye, thermal imaging permits corrective action to be taken prior to costly system failures . Thermal imaging cameras are a unique devices that determine when and the exact spot where maintenance is required, for electrical and mechanical installations are likely to get hot before they fail. By discovering these hot-spots with a thermal imaging camera, preventive action can be promptly taken. This will efficiently prevent costly manufacturing breakdowns and even worse, a disastrous fire. A thermal imaging camera is a dependable remote instrument which is ready to scan and visualize the temperature distribution of all surfaces of equipment and electrical tools rapidly and precisely. Thermography applications have contributed to substantial financial savings all over the world.
