High-quality optical lens, equipped with 256x192 high-resolution infrared sensor, excellent imaging effect. 25Hz high frame rate imaging, smooth picture flow without lag. Used with mobile APP, it supports taking photos ,videos and storing them in the photo album, allowing professional thermal imaging analysis anytime and anywhere. Add points, lines and rectangular boxes for regional temperature measurement. Lines and rectangular boxes support high and low temperature tracking and high temperature alarms. Wide temperature measurement range: -15℃-600℃; Automatic temperature tracking, supporting high and low temperature and center point temperature tracking. Model:T7 Resolution:256 x 192 Wavelength:8-14um Frame rate:25Hz NETD:Less than 50mk 25℃ FOV: 56°x 42° Lens:3.2mm Temperature measurement range: -15℃-600℃ Temperature measurement accuracy: ±2℃ or ±2% Temperature measurement:Highest,lowest,central point and areatemperature measurement are supported Color palette: lron,white hot,black hot,rainbow,,coldblue Working temperature:-10℃-75℃ Storage temperature:-45℃-85℃ IP rating:IP54 Note: In order to correct non-uniformity, a mechanical control calibration plate is installed in front of the thermal imaging detector, which be calibrated every 10 seconds to more accurate measurements. Usually, there is a pause of about 1-3 seconds which is caused by the thermal imaging detector calibration . This is a normal phenomenon, please don't worry. Notice: Using mobile phone thermal imaging in normal environments (prohibited in harsh environments such as high temperature and high magnetism).
