Abstract
A pH-meter capable of measuring conductivity and dissolved oxygen at the same time is composed of a gauge and three probes. Three power sources and three measuring circuits are mounted to the gauge. The detectors of the probes include a pH detector, a conductivity detector and a dissolved oxygen detector. Each of the probes is independently connected with the gauge via a transmission cable to be independently supplied with electricity and the signals of two probes are independently transmitted by electric insulation. Thus, the detecting elements can measure the pH value, conductivity, and dissolved oxygen at the same time with interference with one another.
