The PHE-5432 is a steam-sterilizable combination pH electrode designed to withstand high temperatures and pressures. The use of a porous PTFE liquid double junction and specifically formulated low impedance glass membrane allows it to function in the broadest spectrum 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 this demanding environment.
