If the BPB sensor is not to be soaked in KCL, then why is there a fill line on the PC60 that surpasses the point of the BPB sensor?
The fill line on the probe cup is the minimum volume for tested sample in the probe cap, not for the storage solution. The BPB conductivity sensor should ...

What is this Crystal liquid oozing out of my PH60S cap and does it mean my meter is damaged?
The liquid that is stored in the cap is Potassium Chloride (KCL). It tends to crystalize once it leas out tof the probe. The crystals are non-hazardous su...
