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.

: a new sensor for long term Ambulatory pH monitoring" Gut, 1991, 32, 240-245.
Ensure the glass bulb of the pH electrode
is hydrated before performing a calibration.
ENDRESS+HAUSER has announced it has achieved MCERTS certification for its CM44x analytical transmitter and associated CPS11D pH electrode
. The award follows both laboratory testing and a field test on the effluent from a wastewater treatment works.
Designed to make it quick and easy to choose the right pH electrode
for any laboratory application, theThermo Scientific Orion pH Electrode
Selection Guide is an interactive guide that helps the user select the most appropriate pH electrode
to meet their indicated needs and budget.
A pH electrode
and gamma detector were accurately positioned 5 cm above the cardia.

," Rare Metal Materials and Engineering, vol.
Furthermore, the slope of the internal pH electrode
in the new [CO.sub.2] sensor is very stable, even after sterilization.
The PH12 sensor family is available in the PEEK or a glass body, either of which is available with a high-performing flat, ruggedized glass pH electrode
or a domed pH electrode
The pH electrode
is an active transducer requiring energy for its operation.
The following specification must be made: the measurements cannot be effected on the integral blood, because the existing "residues" (including the red cells) load the pH electrode
