Features:  - Dual Function: Combine the functions of surface temperature measurement and real-time thermal imaging.   - Time Saving: No need to measure each component one by one anymore, saving your time.  - High-definition Images: With the 2.8" 160*120 full color display screen, this thermal camera can help you observe the full range of infrared images.  - Image Overlapping: Image overlapping makes it easier for users to understand the infrared images by using aligned visible images and infrared images. The use of image overlapping can capture the visible image of every infrared image so as to display the temperature distribution in the target region correctly and share with other people more effectively.  - 5 Color Imaging Modes: Rainbow, iron oxide red, cold color, white heat and black heat. The monochrome palette makes it easier to spot subtle differences, while the high contrast palette helps you quickly find obvious anomalies. Capable of choosing the ideal color palette according to your different needs.  - & 8451;/& 8457; Switchable: The temperature range of this infrared camera is -20& 8451;~450& 8451;(-4& 8457;~842& 8457;), and you can switch units of Fahrenheit and Centigrade in the Settings.  - Image Output: The saved images through capture may be checked and output by connecting with a computer through Mirco USB.  - Wide Applications: Ideal for car engine overhaul, transformer room line maintenance, air conditioner repair, etc. in electric power, electronic manufacturing, industrial inspection and other fields.    Specifications:  Brand: wintact  Model: WT3160 / WT3220 / WT3320 (Optional)  Material: ABS  Color: Red+Black  Plug: EU  Power Supply: Rechargeable 18650 battery  Duration: 2-3 hours  Automatic Power-off: 5mins / 20mins / manual shutdown (Switchable)  Display Screen: 2.8" full angle TFT display screen  Infrared Image Resolution: 160*120 / 220*160 / 320*240 (Optional)  Temperature Measurement Range: -20& 8451;~450& 8451;(-4& 8457;~842& 8457;)  Measurement Accuracy: ±2& 8451;/±2% (Greater than 300& 8451;, the accuracy is ±5%)  Visible Image Resolution: 300,000 pixel  LCD Resolution: 320*240  Shortest Focusing Distance: 0.5m  Emissivity: Adjustable from 0.01 to 1.00  Frame Rate of Thermal Images: 9Hz  Wavelength Coverage: 8-14μm  Storage Capacity: Built-in 3G (above 20,000 images stored)  File Format: JPG  Language: English, Chinese, Italian, German  Working Environment: 0& 8451;~45& 8451;, <85%RH  Storage Environment: -20& 8451;~60& 8451;, <85%RH  Item Size: Approx. 22.5*8.9*6.7cm / 8.86*3.5*2.64in  Item Weight: Approx. 332g / 11.71oz  Package Size: Approx. 26.2*13.2*9cm / 10.31*5.2*3.54in  Package Weight: Approx. 968g / 34.15oz    Packing List:  1 * Thermometer  1 * Adapter (EU)  1 * USB Cable  1 * Hand Strap  1 * Storage Bag  1 * Users Manual(English)
