S650/S651 Series Submersible pH and ORP Electrodes Description

The submersion pH and ORP electrodes from Sensorex are designed for measurements in tanks, flumes and sewer lines. Submersion designs are also well suited for high suspended solids applications, flocculation operations which require low velocities, or in tanks with high agitation.

Where low velocities are present and coating is a problem, the electrode can be mounted at a 45 degree angle facing into the flow so as to obtain increased scrubbing action across the measuring surface.

The cartridge quick disconnect design makes changing electrodes a snap and minimizes down time due to electrode maintenance.

Model S651CD offers a pH glass protection feature and the extra performance of acrylamide reference gel.
