An all in one thermal Camera Portable thermal imaging device for quick temperature scans of electrical equipment, machinery and other assets 25Hz refresh rate (most are 9Hz), which allows for smooth tracking of moving objects 320 × 240 pixel screen LCD Includes a 32 GB built-in SD Card & 6 hour battery life Affordable Personal thermal imagers built for the field YJ 256 All in One Thermal Camera Diagnosing electrical units is difficult sometimes. Most often, when we find problems we see, it becomes too late to diagnose. There is a long list of all of the different things you can do with the YJ256 including inspections of properties, vehicles, machines, piping and much more in order to assess their physical state. With a high resolution of 256x 192, images are crisp and detailed It uses visible light camera to create a layered image that includes both visual and thermal information It has a decent thermal sensitivity of Temperature range High-gain: -20°C~150°C; low gain: 150°C~550°C Measurement resolution 0.1℃ Accuracy +2*C/±2% (whichever is greater) Response time ≤500ms Pixel size 12μm Infrared spectral bandwidth 8μm~14um Field of view (FOV) 56°(H)x42°(M) Spatial resolution (IFOV) 3.8mrad Thermal sensitivity <60mK Frame rate <25Hz Temperature measurement mode ROl, center point temperature, high temperature tracking (default) Image mode Thermal, Digital camera (visual light), Fusion, PIP Visual light resolution 640x480 pixels Image blending ratio 0% (pure visual light image).25%,50%.75%， and 100% (pure infrared image) PC software Yes Real-time image transmission Yes (real-time image projection through PC software)
