Cole Parmer Self-Cleaning Retractable Ph Electrode With Cpvc Housing

Rugged combination electrodes with flat measuring surfaces are ideal for industrial pH applications. In both coating and abrasive applications these cartridge type electrodes can improve measurement accuracy, reduce maintenance, prolong electrode life and virtually eliminate breakage. Electrodes have a unique and innovative design. In the center of the measuring surface is the pH-responsive flat glass surface. This surface is surrounded by the flat porous plastic reference junction. The large area of this porous junction has thousands of pores that provide excellent sample contact. Built into the electrode’s body is a sealed, gel-filled double junction reference design. This design provides an extra barrier against reference side contamination. Also, it allows the electrodes to be used in applications where sulfides, mercaptans, heavy metal ions and similar materials are present. The insertion assembly allows pH measurements to be made in pressurized tanks and main lines without the need for system shutdown for electrode maintenance. Insertion depth is adjustable to 12" allowing it to be positioned in a turbulent flow region so as to operate in the self-cleaning mode. Assemblies can be mounted in any direction—even upside-down. A 1" full-port ball-valve is recommended for initial installation.
