The authors' carried out a pHmetric study of stomach, esophagus and gastroesophageal junction in dog, using four techniques: intermittent pull-through technique, continuous pull-through technique, continuous push-through technique and rapid pull-through technique. The study was done in six adult male dogs. Each animal was studied in five sessions, having been undergone 16 examinations and having been done 4 examinations of each technique. The intermittent pull-through technique (TPI) proved to be the most adequate for the pHmetric study, because it propitiates better interaction conditions between electrode and environment. Of the techniques of continuous dislocation, the continuous push-through technique (TEC) presented the most satisfactory results, having the electrode presented little latency. The continuous pull-through technique (TPC) has its application on the dependence of the pull speed; it was observed that the less the speed the less the latency of the electrode. The rapid pull-through technique (TPCR) doesn't permit an adequate interaction between electrode-environment, in consideration of the rapidity of the examination.
