Features: HT-18 is a inferred camera that integrates surface temperature measurement and real-time thermal image. The traditional inferred thermometer needs to measure every component one by one while it is not necessary for thermal image, thus saving time. The potential problems may be displayed on color display screen clearly. This is helpful for users to locate the measurement cursor of the central point quickly and measure the temperature. In order to increase the differentiation degree, the product is provided with a visual camera. The thermal images and full vision images can be stored in the device and can be called through USB or saved in a computer to generate report and printing. HT-18 is easy to use; Test may be conducted in several seconds after powering on. The product can be used in fields of medical treatment, fire fighting, archaeology, traffic, agriculture, geology, energy, smelting, electronic manufacture, etc and is the ideal selection for electrician and maintenance personnel and technicians and can be used to find the problem area quickly.
