Yep, I would rinse it.

BlueBear Reviewed by BlueBear on . Ph Meter Question... I got a Phep4 Ph Meter today thu ebay. I went to my local grow store and bought Calibrating solution as well as electrode storage solution. As I was told I would definetly need these. Downlaoded the manual, read it understand that the Ph meter has to be cal 'ed and you must keep a drop or 2 of the electroide solution in the cap so it keeps the electrode moist so it doesn't dry out. Why can't it dry out? Is that electroid like gold? Is it super sensitive? Should I not run it directly Rating: 5
