title: State-of-the-art medical pH probes.
abstract: 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.
