The PHE-5432 is a steam-sterilizable combination pH electrode
designed to withstand high temperatures and pressures. A porous PTFE
liquid double junction and specifically formulated low-impedance glass
membrane allow it to function in a wide variety of pH applications. This
combination of features permits extended periods of pH measurement in
the presence of poisoning ions or where membrane leaching would shorten
the life of a conventional electrode. Melting of the cable due to contact
with steam lines and motion-generated noise are common problems with
interconnecting cables on steam-sterilizable electrodes. Our proprietary
TPE high-temperature/ultra-low noise cable is designed for optimal service,
even in demanding environments.
