Mixing and controlling the pH of citrate and phosphate with website

In this study built an instrument capable of mixing and controlling chemical pH citrate solution phosphate as buffer solution. The problem often experienced in chemicals is a matter safety the accuracy concentration substance. function to mix control It hoped that presence instrument, manufacture solutions can be carried out electronically which does not involve manual calculations obtain desired solution, relatively safe from direct contact with chemicals. This using sensor sensing value made. And controller used microcontroller. Results other than stored database, also transmitted internet (website) wifi interface device. Mixers controls have been realized resulted good control.
