OMEGA Engineering, Inc. Retractable pH Electrode PHE-6820 / PHE-6821

The PHE-6820 electrode and assembly features a retractable design for insertion into tanks and main lines. The assembly, when used with a 1" full port or larger ball valve (user supplied), allows the electrode to be removed without shutting the system down. This electrode can be mounted in any location, even up through the bottom of a tank with the electrode surface facing upward. Its unique design affords mounting in any direction and is suitable for most systems' inherent design. (This style is also available for ORP measurements.)
