A thermal camera, also known as an infrared camera, is a device that uses infrared radiation to create an image based on temperature differences. It can detect and measure the amount of heat emitted by objects, allowing it to identify hot and cold spots, and provide a visual representation of temperature variations. This technology has a wide range of applications, including in surveillance, medical imaging, building inspections, and industrial processes.

An SF6 analyzer is a device used to measure the concentration of sulfur hexafluoride (SF6) gas in various applications such as electrical transmission and distribution equipment, industrial processes, and medical applications. SF6 gas is a potent greenhouse gas, and its concentration in the atmosphere is regulated by various international agreements due to its potential impact on climate change. SF6 analyzers typically use infrared absorption technology to measure the concentration of SF6 gas accurately. They are used by engineers, technicians, and researchers to monitor and control the use of SF6 gas in different applications.
