| Popis: |
A galvanic cell consisting of a silver-lead couple separated from the test sample by an oxygen permeable plastic membrane provides the basis of a simple oxygen analyzer. The current generated, while directly proportional to the amount of oxygen in the sample, also depends upon factors such as temperature, membrane thickness, kind and concentration of the supporting electrolyte, and the geometry of the cell. The analyzer has been used successfully with continuous recording devices and as a completely portable instrument with a readout on a microammeter for oxygen monitoring in natural waters and wastes. Oxygen content in non-aqueous systems and gaseous streams may be measured by the device. |
