The Ammonia Gas Sensing Probe - pH Electrodes - Sentek

Gas-sensing probes are complete electrochemical cells consisting of a pH and a silver-silver chloride electrode (Fig. 1). The glass electrode is separated from the sample by a thin film. Any change in the partial pressure of ammonia in the thin film causes a change in response at the glass electrode, which is registered on a mV meter.
