Insertion Mounted pH Electrodes

Because of it's cost effective CPVC construction, the Sensorex Insertion Assembly allows pH measurements to be made in pressurized tanks and main lines without having to use expensive stainless steel components.

The insertion depth is easily adjustable by the user, to be positioned in an turbulent area of the tank or line.  This will optimize the self cleaning feature of the flat surface electrode.  In abrasive applications, the electrode is usually positioned close to the pipe wall. This assembly is well suited for measurements in liquids with high suspended solids and for measurements in viscous liquids.

The insertion assembly can be fully retracted through an optional 1" full port ball valve, (Sensorex part number BV-1).  The ball valve is then closed, isolating the electrode and holder from the pressurized system.  This is accomplished without draining the tank, or de-pressurizing the line.

The special electrode used in the Insertion Assembly allows it to be mounted in any position; for example, even through the bottom of a tank with its measuring surface facing upward.  The vast majority of pH electrodes in the world should be installed above the horizontal plane, due to the intentional placement of an air bubble in the pH stem  (The air bubble compensated for pressure changes due to thermal expansion and contraction)
