The PHE-5580-20 and PHE-5590-20 are wet or dry steam sterilizable pH electrodes constructed of a durable high temperature thermoplastic with a 316 stainless steel jacket. The outer body is fitted with a 3/4' MNPT mounting thread. The use of a double Porous PTFE liquid junction reference cell and specifically formulated low impedance glass membrane allows use in the broadest spectrum of pH applications. This combination permits extended periods of pH measurement in the presence of poisoning ions, or where membrane leaching would shorten the life of conventional electrodes.
Application • General Industrial Service • Chemical Production • Electro-Plating Baths • Waste Treatment Processing
