ABSTRACT:
A method of thermal protection of a membrane-enclosed amperometric cell of the type comprising an electrolyte within an electrolyte space containing electrodes and enclosed by a semipermeable membrane which defines a sensor face; heat exchange within said cell is effected for controlled heat compensation of the electrolyte when the sensor face is exposed to temperatures outside of the operative temperature range of the cell.
A membrane-enclosed amperometric probe having an elongated body provided with a sensor face at one end of the body and with electrical electrode connections extending through the probe body; the body includes at least two elongated fluid-passing channels formed between a pair of coaxially arranged interfitting tubular members that extend in axial direction through the body from a first region near the one body end to a second region near the other body end; the channels have mutually communicating ends in the first region and separate fluid-feeding ends in the second region so as to permit passing a fluid through the probe body.
