Sampling rate is around 10KHz and is expected to increase while ongoing development. This will occur where precision will matter. How the multiplexing is done inside ? If it's a constant amount then I can correlate the results at PC software side otherwise I guess I will need to increase the budget and upgrade to a better platform.
