Versatility of Thermal Imaging Tool

The Fluke thermal imager works by detecting head from a person or object. It's also called an infrared camera and its lens will bounce off the waves from infrared energy into the sensor array. These sensors then convert the energy into signals which then form the video image. A person who emits heat will appear as a white image while the immediate surround will look gray.
Can a thermal imager see through walls and clothes?
This is one of the misconceptions about the Fluke or Trotec thermal imager. The simple answer is no, they can't see through walls nor can they see through a person's clothes. The lens can't even "see" the person just like you would in visible light. What is picks up is the heat signature of the person or object. It's been used in construction as well as air-conditioning or heating industries because the device can spot fissures and cracks where warm or cold air can seep through increasing your energy bill in the process.
In law enforcement, however, the imager can be used to detect a gun through a person's clothes because the signature will appear cooler to the camera which may alert the police about the firearm.
Industrial use
Hotspots in manufacturing plants are very dangerous because they will lead to mechanical or electrical failures. So the power control center or the electrical cabinet is always monitored and checked for any of these hotspots. Through the use of imager, the business owner can save money by extending the lifespan an increasing the efficacy of the machines.
By the way, it used for a long time by border security patrols in order to detect smugglers or illegal immigrants even in the dead of the night. Prison houses will also benefit from the technology as they can immediately spot jail breakers much better than CCTV cameras can. Some imagers can "see" a person as far as 20 kilometers away.
Security in commerce
Just like border patrols, Trotec thermal imager can also be utilized to secure airports, ports, warehouses, manufacturing plants, shopping malls or just about any commercial establishment. You can save money by cutting on the number of security personnel on foot patrol as they can stay in a safe place and monitor the perimeter with the infrared cameras.
Calibrating thermal cameras
Just like any measuring tool, infrared cameras also need to be calibrated and checked for accuracy. This is very important in order to know if the device still works particularly when used in high risk environment like plants with high electrical radiation or the presence of gaseous substances. You can avail of service by providers in calibrating your thermal imagers through their testing tools.
