The mobile phone thermal imager is a portable thermal imaging product of long-wave infrared (8~14μm, LWIR), which can convert the thermal radiation of the measured object into images and temperature data. Main functions: 1. Supports ultra-high infrared resolution of 256X192 pixels, and displays thermal images in real time and high definition through 25Hz high frame rate. 2. Supports measurement of the full temperature range of -20℃~550℃ (-4℉~1022℉), and can accurately detect temperature changes of 0.1℃(32.18℉). 3. Supports real-time image photography and video recording, and can set the maximum\minimum\center temperature value display of point, line, and surface areas at any position on the image. 4. Supports thermal imaging\fusion\picture-in-picture mode switching, combining infrared images and visible light images. 5. Supports real-time temperature sound/light alarm, and can customize high or low temperature alarm values and alarm modes. 6. Support real-time temperature waveform monitoring, you can set points, lines, and surface areas at any position on the image for temperature monitoring, automatically save temperature monitoring videos, support video playback and excel table data export. 7. Support the generation of temperature measurement analysis reports, you can select any photo in the album to generate a PDF report, and support PDF report sharing.
