VK701USB four-channel isolated 24-bit data acquisition card

VK701 USB 24-bit data acquisition card

    VK701 is a USB type high-speed 24 bit data acquisition card. The VK701 acquisition card has features such as true differential input, 4-channel synchronous acquisition, sampling accuracy up to 24-bit, 400 ksps sampling rate, precise pre gain, and USB photoelectric isolation. The VK701 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.
