[Apparatus for the multichannel pH measurement of the upper section of the gastrointestinal tract].
To study simultaneously the acid-base processes in the esophagus, stomach and duodenum a procedure involving the use of multichannel pH measurements is proposed and a setup designed whose basic elements are a 6-channel pH-probe and a registering device. A visual and graphic registration of the investigation results is envisaged.
