Symmetrical mode:

For noisy electrical environments, the alpha pH 190 controller offers

Symmetrical Mode operation. To take advantage of Symmetrical

operation, you must have an electrode with a solution ground

(potential matching) pin, such as the EC-ARGTSO-05B or EC-

100GTSO-05B.

If your electrode does not have a solution ground, be sure to set the

controller to Asymmetrical mode.

Symmetrical mode avoids grounding the reference electrode by

reconfiguring the input to a floating differential mode. The electrical

noise appears equally on the pH and reference electrodes, and is

therefore rejected by the operational amplifier.
