    Product Introduction

    EM640 Infrared Thermal Imager combines surface temperature measurement and real-time thermal imaging. Unlike traditional infrared thermometers that require measuring components one by one, it saves time. Potential problems are clearly displayed on the color screen, and the center-point measurement cursor quickly and accurately locates and measures the target temperature.
    Thermal images can be saved to this device, read via USB or saved to a computer for generating reports and printing. This product is small in size, easy to operate and highly functional. It is an ideal choice for fields such as power, electronic manufacturing and industrial inspection. The ETB640 infrared thermal imager can adjust the radiation coefficient to improve the accuracy of measuring objects on semi-reflective surfaces. The highest and lowest temperature cursors can guide users to the areas with the highest and lowest temperatures in the thermal image. There are 7 color palettes to choose from. These functions enhance the measurement accuracy and usability of the product.
    ETCRMETER is a high-end brand of ETCR. All products are manufactured by ETCR, which also provides technical support and after-sales service.
