VK702H USB 24-bit data acquisition card

VK702H USB 24-bit data acquisition card

    VK702H is a USB type high-speed 24 bit data acquisition card developed by Shenzhen Vkinging Electronics Co., Ltd. The VK702H acquisition card has features such as true differential input, 8-channel synchronous acquisition, sampling accuracy up to 24 bits, maximum 800 ksps, and precise pre gain. The VK702H USB uses multiple high-precision 24-bit ADC units and a front-end differential amplifier module developed in cooperation with our company for many years, making this product have the advantages of high speed, high resolution, high accuracy, ultra-low noise, high common mode rejection ratio, wide measurement range, and low temperature drift. It is suitable for various occasions of precision high-speed acquisition.
