Flat Surface pH Electrode Operating Principles From Sensorex
Sensorex - Flat Surface pH Electrode Operating Principles
Sensorex pioneered the development of the Flat pH Sensitive Glass Electrodes and has been the leader in supplying this design to industry for 20 years. All of Sensorex Flat Surface Electrodes are combination pH/Reference (or ORP/Reference) electrodes with double reference junction for added protection against contamination.
In the center of the measuring surface is the pH-responsive flat glass surface. This surface is surrounded by the flat porous reference junction. The large area of this porous junction has thousands of pores that provide excellent sample contact.
The junction is enclosed by the electrode body. At the top of the electrode body is the quarter- turn, quick disconnect BNC connector and the leak-tight O-ring seals. All replacement electrodes are supplied complete with O-rings.
The flat sensing surface is rugged, abrasion resistant, and self-cleaning. In both coating and abrasive applications these cartridge-type electrodes can improve measurement accuracy, reduce maintenance, prolong electrode life and virtually eliminate breakage. Typical applications for this type of electrode include:
Self Cleaning Operation
Abrasion Free Operation
Particles sweep by the electrode's flat, non-protruding surface without impinging on or abrading it--extending electrode life. The non-protruding design virtually eliminates electrode breakage. Particles impinge on the upstream side of the spherical bulb, causing abrasion, calibration shift, and short life.
