Features: Infrared thermal imager that can blend the visible and infrared images. Higher resolution of infrared image/visible image: 320x240/640 * 480 (300,000 pixel). Integrates surface temperature measurement and real-time thermal image with non-contact target. This infrared imaging device is professional, precision and efficient with a visible light camera. 3.2" full angle TFT display screen can get the information you need more clearly. For car engine overhaul, transformer room line maintenance, air conditioner repair, etc. Turn thermal image into visional image, quickly find out the problem area. The thermal images and visible images are stored in the device and can be read through USB or stored in a computer to generate a report or for print. Can be used in fields of medical treatment, fire fighting, archaeology, traffic, agriculture, geology, energy, smelting, electronic manufacture, etc. Perfect tool for electrician, maintenance personnel and technicians, and can be used to find the problem area quickly. The buttons on the thermal imager body are clearer and easier to operate. Equipped with a hanging rope and a protection bag for easy carrying. The following major functions increase the product's accuracy and usability:  1. The adjustable radiation coefficient increase the measurement accuracy of half reflection surface.  2. The thermal point and cold point temperature mark may guide the users to the area with highest or lowest temperature of thermal image.  3. The selectable color palette.   Specification: Input Voltage: AC 100-250V, 50/60Hz Material: Plastic + Rubber Color: Black Material: ABS Display Screen: 3.2" full viewing angle high-resolution color TFT screen  Infrared Image Resolution: 320x240 Visible Image Resolution: 640 * 480 (300,000 pixel) Field Angle/Shortest Focus Length: 26°*34°/0.15m Thermal Sensitivity: 0.07& 8451; Measuring Mode: Thermopile Temperature Measurement Range: -20& 8451; to 300& 8451; (-4& 8457; to 572& 8457;) Measurement Accuracy: ±2% / ±2& 8451; Emissivity: Adjustable from 0.01 to 1.0 Frame Rate of Thermal Images: 9Hz Wavelength Coverage: 8-14μm Focus Mode: Fixed Imaging Distance: 0.5-40m Color Palette: Rainbow, iron oxide red, cold color, black & white, white & black View Option: The integration of thermal image with 25% step length and visible image Storage Medium: Built-in 3G (Above 20 thousand images stored) File Format: JPG Set Control: Unit Adjustment/Language/Date Time Format/Automatic Power-off Time USB: Micro USB 2.0 Battery: 1 * Built-in Rechargeable 18650 3.
