Short electrode service life? Electrodes shift when system is running? You may have a ground loop in your measurement system. Ground loops are fairly common and Sensorex has simple solutions to solve these issues.

Low Ionic pH applications can cause pH electrodes to appear unstable and sensitive to drift. Sensorex offers special models in low ionic configuration to help solve these issues.

Sensorex self-cleaning flat surface combination pH electrodes are available in fluoride resistant designs. A special glass formulation is used to enhance the resistance of the pH glass from fluoride attack, resulting in an extended life and reduced maintenance cost.

Sensorex pioneered the use of the Flat pH Sensitive Glass Electrodes and has been the leader in supplying this design to the industry for 20 years. All of Sensorex Flat Surface Electrodes are combination pH/Reference (or ORP/Reference) electrodes with double junctions.

Sensorex offers process flat surface pH electrodes & holders in PPS, CPVC or PVDF. PPS is ideal in water and chemical processes up to 100°C. CPVC is useful in water-based applications under 80°C.  PVDF offers improved organic solvent resistance. Learn more about materials available.
