Integrated Ground Loop Interrupt pH Electrodes

Plastic tanks and piping are particularly susceptible to grounding problems, because of poor earth grounding. Dirty motors from electrically driven pumps or mixers, other electrical equipment and even conductivity probes leak voltage into the solution which feeds through the pH electrode and electronic circuit.  This leads to invalid readings and shortened electrode life.

The DA series electrode combats these problems by utilizing a solution ground pin and internal battery powered ground interrupt circuit. The battery has an estimated 2 year service life. The DA series electrodes are part of our Flat Surface, self cleaning series quick disconnect designs which offer all the benefits of our time tested and proven self cleaning series and more! 

The classical diagnostic symptom is when the system calibrates and works fine outside of the tank or line, but drifts or reads incorrectly when installed in the system. 

The battery powered internal amplifier permits long cable runs to be used between the electrode and the transmitter-controller, even 1,000 feet or more !

These cost effective electrodes are mounted into standard Sensorex gland fittings and can be used for submersion installations as well as in 3/4", 1" and 2" size pipe tee's.  They use our standard cap cables for ease of use.  Special Fluoride Resistant versions are also available.
