How is the best way to clean fouling from Yokogawa conductivity probes? ? The probe appears to be made of metal. How to remove scale? Can acid washing be used? The probe must not be damaged. Experienced teachers, please share a little of your experience.
For a conductivity probe designed to measure low conductivities, the probe’s electrodes are made of stainless steel or titanium. First, it is necessary to know what the scale formed is composed of Is it carbonate scale or silicate scale? If it is carbonate scale, it can be soaked in a dilute weak acid solution for some time, then cleaned thoroughly; after re-calibration, it should be usable again. If it is silicate scale, it is difficult to handle; in that case, replace the probe.
From a technical perspective, I think it’s rust and calcium/magnesium compounds. Just like limescale in tap water. Is recalibration needed after cleaning?
