Where pH is measured, there is a risk of electrode fouling; result is a drift of measured value. To be free of this, it is necessary to clean carefully the electrode.
For this purpose, we designed the auto cleaning probe 9360 to inject pressurized cleaning liquid on the electrode to remove impurities.
For instance: injection of hydrochloric acid to remove sodium carbonate.

The probe 9360 accepts our electrode holder "probe 9336" (data-sheet 130-01). Tubing for cleaner liquid is all inside the probe body.
Auto-cleaning probe may be adapted at anytime on existing pH immersion probe 9336.

The cleaner fluid, water or acid + water, is projected through 3 nozzles around the electrode, 2 mm close to the bulb.

Fitting of the probe consists of an adjustable flange. The sliding ND 65 mm flange, allows adjustment of immersion depth. Only the immersion probe 9336 may be used with the system 9360.

The cleaning sequence is set up by our BAMOPHAR or BAMOPHOX monitors. During the cleaning routine, regulation is switched on "STAND-BY", not to interfere with the process.
