Infrared Thermography


Infrared Inspection CameraThermal images, or thermograms, are actually visual displays of the amount of infrared energy emitted, transmitted, and reflected by an object. Because there are multiple sources of the infrared energy, it is difficult to get an accurate temperature of an object using this method. A thermal imaging camera is capable of performing algorithms to interpret that data and build an image. Although the image shows the viewer an approximation of the temperature at which the object is operating, the camera is actually using multiple sources of data based on the areas surrounding the object to determine that value rather than detecting the actual temperature. Gathering information and inputting that information into the camera's computer can only be done by a trained and certified thermographer.

What is a thermographer?

A thermographer is a thermal evaluator and imaging expert. He or she will have a solid understanding of heat transfer laws, thermal dynamics and properties of why objects are hot or not or appear to be hot or not.

A thermographer is a person who uses an Infrared Camera and his or her knowledge of the subjects they look at in combination with other non-destructive testing tools to evaluate the condition, (good or bad) of any object, subject or body in the world at large today... as long as there is a thermal difference to be detected. Otherwise objects with the same thermal radiant pattern or temperature will be invisible to each other.

Our Equipment:

We utilize the FLIR T400 infrared camera which delivers 320 X 240 IR resolution or 76,800 pixels. This, combined with FLIR's exclusive Advanced Signal Processing, reduces image "noise" and produces razor-sharp thermal images with four times the resolution of competing brands with 160 x 120 resolution. With the 3.1 mega pixel visual camera, the FLIR T400 infrared camera can simultaneously capture thermal and visible images. The FLIR T400 infrared camera also includes a target illuminator for low light situations. Markers using touch screen technology can be drawn directly on the visual image. Our high temperature model is capable of measuring temperatures up to 2192° F.

The FLIR T400 is equipped with METERLiNK™, an exclusive wireless technology that records essential meter readings at a job site directly onto your infrared images. METERLiNK™ connects your FLIR camera with select Extech meters via Bluetooth, transmitting readings that add value and insight to your infrared inspections and reports.

FLIR's new FUSION functionality allows for easier identification and interpretation of infrared images. This advanced technology enhances the value of an infrared image by allowing you to overlay it directly over the corresponding visible image. This functionality combines the benefits of both the infrared image and visual picture at the push of a button. The FLIR T400 infrared camera does this in real-time and the overlay function can be easily adjusted to suit any application such as electrical surveys, building diagnostics, and mechanical inspections.

The FLIR T400 infrared camera offers both auto and manual focus. Featuring a powerful one-touch continuous digital zoom (8X zoom) to zero-in to the optimal view, the the FLIR T400 infrared camera comes with a built-in standard 25° lens and we utilize a 45° wide angle lens for many applications.

The FLIR T400 infrared camera features a Delta temperature mode. Just place a reference spot on a target operating at normal temperature and another on the target with elevated temperature. The Delta temperature function immediately displays the difference between these two targets on the image making it easy for to diagnose the severity of the problem. The image can then be stored with these measurements and incorporated into reports.
