Thermal Imaging System for Electronics Testing

Whether the goal is product testing or scientific research, heat can be an important indicator of how a system is functioning. The FLIR ETS320 is a non-contact thermal measurement system that pairs a high-sensitivity infrared camera with an integrated stand, for hands-free measurement of printed circuit boards and other small electronics.



ETS320 takes the guesswork out of thermal testing for fast discovery of hot spots and potential points of failure. This sensitive camera detects minute temperature shifts (< 0.06°C) and quantifies heat generation up to 250°C.



The ETS320 offers 76,800 points of non-contact measurement, so researchers can locate hot spots without concerns about unseen heat sinks. Temperature measurement accuracy of ±3°C helps to ensure products attain quality assurance and factory acceptance.



FLIR designed the ETS320 for hands-free use in a lab, with a microscope-style stand that's quick to set up and simplified features that allow researchers to focus on their work instead of on camera controls.


It used to be time-consuming to measure every location on our test units for hot spots. Now with FLIR, we can quickly identify all of them and focus our time-consuming testing at fewer points with greater confidence that none was missed.

The ETS320 is great because it's mounted in such a way that it's very easy to just place something under it and take your hands off it and electrically probe the PCB if you need to, it's steady.
