in thermistor for temperature measurements
and compensation. The thin permeable
membrane isolates the sensor elements from
the testing solution, but allows oxygen to enter.
When a voltage is applied across the sensor,
oxygen that has passed through the membrane
reacts causing current to flow, allowing the
determination of oxygen.
