if the sensor tip on the Milwaukee pen dries out, it's trashed :wtf: ... do NOT store it with calibration solution in it, or distilled water, either ... store it with plain tapwater ... (this, straight from the manufacturer) ... :smokin:
the image reaper Reviewed by the image reaper on . Questions about PH pen... Whats up... Just bought a new Milwaukee PH 600 pen and I have a couple questions. Since this is my first pen... I calibrated it to 7.0 with the solution it came with. Tested my res with it fine. I washed it and put a small piece of sponge in the cap with the storage solution. The next day now the PH was crazy on the pen... My question is, Does it need to be calibrated before every use?? Also did I use the storage solution correctly? It didnt come with any instructions really.. Rating: 5
