State-of-the-art medical pH probes.
This article deals with the development of reusable peroral, transnasal, and endoscopic pH probes, and it looks into the operational features of pH probes equipped with silver-chloride distal and surface reference electrodes. The results obtained revealed that pH probes with a surface reference electrode offer a number of advantages over pH probes with a distal reference electrode.
