The HT641B is a very accurate infrared thermometer that uses a laser to measure the surface temperature of objects quickly and easily. The laser can be aimed at hot surfaces or moving objects, allowing the user to easily capture the temperatures being measured from a safe distance. The device is activated by a trigger and takes a precise temperature reading in a flash.

The HT-03 infrared camera integrates surface temperature measurement and real-time thermal imaging. The traditional inferred thermometer needs to measure every component one by one while it is not necessary for infrared imaging camera, thus saving time. The potential problems may be displayed on color display screen clearly. Moreover, the central point measurement cursor is used to locale quickly and accurately to measure the temperature of the target object. In order to increase the differentiation, the HT-03 is provided with a visible light camera. The thermal images and visible images are stored in the device and can be read through USB. The HT-03 is easy to operate and it is the ideal selection for electric power, electronic manufacturing, industrial inspection and other fields. The following major functions increase the product's accuracy and usability: The radiation coefficient may be adjusted to increase the measurement accuracy of objects with half reflection surface. The highest temperature and lowest termperature cursor may guide the users to the areas with highest and lowest temperature of the thermal images. The selectable color palette.
