The history of thermal imaging cameras dates back to 1929 when the Hungarian physicist Kálmán Tihanyi invented the first ever infrared sensitive camera. This was an electronic television camera designed with the purpose to identify enemy aircraft for the British. Fast forward to 1947, the US Military developed the first infrared line scanner that was designed to be used on cargo planes and bombers during the Cold War. The scanner featured a rotating mirror that could scan a wider surface, make temperature measurements at a single point and produce images that display the reading results.
The process of thermal imaging became widely popular with the release of the movie Predator in 1987, where an alien hunter is able to stalk people by detecting their thermal radiation. These days, thermal cameras are essential tools for maintenance, safety and prevention on many construction sites and other industrial facilities.
Electricians rely on a thermal camera to quickly identify problems in electrical equipment and measure the temperature of machines and appliances. Depending on how hot they are, all objects emit a different amount of infrared energy and the thermal camera is designed to detect that energy, convert it into electrical impulses and create an image. Since the human eye can’t detect infrared radiation, the thermal image allows you to see just how much IR energy your appliances emit. Various manufactures produce different types of thermal cameras that have specific features and uses. FLIR is one of the best manufacturers of thermal or IR cameras that is dedicated to improving their design and performance.
One of the best tools from the FLIR products is the FLIR TG165 – the company’s first infrared thermometer. It basically combines the features of a thermal camera and an IR thermometer to deliver accurate temperature readings and fast performance. The thermometer is designed to make non-contact temperature readings, while the thermal camera has the function to display the relative thermal features of the object as opposed to its surroundings. The FLIR TG165 spot thermal camera has a rugged design and it is water resistant, making it the perfect tool for performing all sorts of temperature readings on construction sites. It comes with a dual laser system that allows you to easily aim towards the target area or object from a safe distance.
With the advanced lasers you are able to detect invisible heat patterns and obtain accurate readings about the temperature and working condition of your machines and other electrical equipment. The FLIR TG165 comes with an 8GB micro SD card where you can store your images and keep track of the obtained data. The camera can make measurements ranging from -25° to 380° and features a 150 K thermal imaging sensitivity. The 8-hour battery life means that this advanced tool won’t fail you when you most need it and can basically last for an entire 8-hour work day.
