摘要： The present invention pertains to an apparatus and a means of constructing a pH sensor that can detect changes in pH levels of humidified gases and liquid samples. When electronically connected to a computerized or analog display means, sensitive quantitative measurements can be obtained. Given the construction of current pH devices available today, there is a need in the field for a novel, miniaturized, self-condensing pH probe that can be used in fluid or humidified gases.

摘要： A potentiometric measuring probe contains an electrolyte (110) as well as a primary reference element (106) and a secondary reference element (108) that are arranged so that the front (148) of an electrolyte deficiency advancing from an opening (112) of the measuring probe arrives at the secondary reference element before it arrives at the primary reference element. The potential difference existing between the primary reference element and the secondary reference element is monitored, and when a predefined tolerance criterion is found to be violated, the elapsed operating time from the point when the measuring probe was put into operation is determined and used as a basis for calculating the remaining operating time of the measuring probe.

摘要： An ion concentration measuring electrode unit includes a body member having a plurality of capillary tubes extending through the body member to provide a plurality of passageways for a sample fluid to be tested. The gaps between the hollow tubes are sealed to maintain an internal solution complimentary to the ion to be measured. An internal electrode is immersed within the internal solution whereby a large internal surface area is provided to enable a reduced impedance in measurement of a sample fluid. An ion concentration meter assembly is thereby provided when combined with a sample flow conduit directing fluid through the body member with a liquid junction connected to the conduit and to a reference electrode unit whereby outputs of the internal electrode and a reference electrode can be used to measure an ion concentration.
