Determination of soil pH using a cartesian coordinate laboratory robot and electronic switchbox

Abstract

A commercially available Cartesian coordinate (gantry style) robot has been programmed to sequentially determine soil/water pH (pH_w) using a desk‐top computer, electronic switchbox, pH meter and a bank of five combination electrodes. All movements of the robot together with pH_w data acquisition are orchestrated by the computer. Once the pH_w data has been acquired, it is stored in an array for subsequent transfer to a Laboratory Information Management System.
