Description
The 2751-7 pH Smart Sensor Electronics processes analog signals from a pH electrode
and transmits digital data via a three wire cable to the 9950-X Chlorine Controller.
The DryLoc
electrode connector quickly forms a robust assembly with the sensor.
®
Smart Sensor Electronics offers broken glass and high impedance detection, manufacturing
electrode data and storage of environmental extremes for temperature and pH levels.
The pH electrode is necessary to accurately calculate Free Chlorine levels in applications
that are above pH 7.1 to a maximum pH level of 8.2. Because Chlorine Dioxide is not
pH dependent, the pH electronics and electrode are offered as an option.
The data stream also includes important information regarding the performance and life
span of the pH electrode. The 9950-X provides the operator with a calculated slope of the
electrode (electrode health) and can detect when the electrode requires cleaning.
The 2751-7 is compatible with 4630-13, 4630-14, 4630-23,4630-24, 4630-33, 4630-34, and
4632-13 only. For all other 4630-XX part numbers please contact the factory for support.
* NOTE: The 9950-X Chlorine Controller is not compatible with the standard 9950 controller.
