DiFluid was founded by Linus Peng, an entrepreneur who dropped out of his PHD program at South China University of Technology after a simple idea: Improving outdated technology by using modern methods to reinvent old laboratory equipment and bring the cost down far enough to put it in the hands of ordinary people.

After releasing his first product, a simple, app connected multi-purpose refractometer that utilized a CMOS sensor rather than the traditional CCD, there was an overwhelming interest by the coffee community. After receiving such a warm welcome, Linus and his team dove deeply into the coffee world, introducing innovation and fresh ideas to coffee enthusiasts, small businesses, and large-scale roasting companies alike.
