Features: HT-02D is a thermal Imaging Camera which combines the functions of temperature measurement and real-time thermal imaging. The traditional thermal Imaging Camera shall measure each component one by one but this instrument does not need to. Therefore, it helps to save our customers' time. Even the potential problems can be clearly displayed on the color screen which helps customers quickly locate the central point to measure cursor and temperature. To improve recognition, this product is equipped with a camera. Based on practical requirements, it can turn thermal image into visional image. Thermal image and visional image can be stored in the dismountable memory card. Adjust the images and store them in PC which are used to generate report or for printing. HT-02D is easy to operate. After seconds it can be tested. This product is the product for electrician and maintainer. It can quickly find out the problem area.
