Feature: 1. Easy To Use: This thermal imager offers high accuracy detection over a wide temperature range from -20??C to +550??C (-4??F to 1022??F). There are 3 optional measurement functions, i.e. centre point, high temperature tracking, ROI (region of interest). 2. 2 Vision Modes Switching: The thermal imager supports 2 vision modes, which can be used to find fault points by comparing two measurement maps ideal for electricians and maintenance technicians to quickly locate problem areas. 3. Comfortable Grip: The thermal imager is designed with a grip that is compact, easy to store and carry, and a comfortable grip for easy measurement at any angle. 4. Wide Application: The thermal imaging camera is suitable for construction, power lines, solar panels, electrical cabinets, motors, engines, bearings and brake pads inspection. Fully functional and reliable, it can also be used for capacitor, HVAC inspection, maintenance of base stations. Metal die casting, metallurgy, fire fighting, search and rescue, night vision, electrical testing, substation equipment, construction, environmental monitoring, petrochemicals. 5.
