Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye. These imaging guns translate thermal energy into a color image that indicates hotter areas as brighter and cooler areas as darker, so it’s easy to identify and diagnose problems on instrument panels, HVAC systems, and other equipment. To review footage at a later date, use them to take photos and videos. The lower a camera’s thermal sensitivity, the more precise heat differences it will detect for more detailed images. All are CE marked as meeting European standards for health, safety, and environmental protection. Some include a calibration certificate traceable to NIST stating they’ve passed a test for accuracy.
