MEASURING DEVICE FOR DETECTING AMMONIA IN GASTRIC JUICE

摘要

The invention concerns a measuring device for detecting ammonia in gastric juice, more particularly a stomach capsule, catheter, gastroscope or biopsy forceps, having a sensor, the sensor comprising: - a reference electrode with a noble metal that is impervious to the acid present in gastric juice; a first measuring electrode comprising silver; a second measuring electrode that comprises silver and is substantially free of a silver chloride layer; means for determining at least one electrical variable that is influenced by the presence of ammonia in the region of the electrodes.
