ABSTRACT:
A sensor which may be immersed in a fluid to measure the pH and the ORP potential of the fluid is taught. The sensor has three solid state electrodes, a pH sensing electrode, a reference electrode and an ORP potential sensing electrode, which extend from a fluid-tight enclosure. The enclosure further contains a display means for indicating the pH measurement and the ORP potential measurement.
