After calibration we inserted a pH/MMI catheter (K6011-E1-0782; Unisensor, Switzerland) transnasally, positioning the lower pH electrode 10 cm below the lower oesophageal sphincter (LOS) and the upper pH electrode 5 cm above the LOS.
The new metal sensor input card allows the use of either a copper or nickel sensor along with a pH electrode. The optional universal sensor input permits exceptional flexibility to use almost any type of sensor including pH/ORP, conductivity, or disinfection.
