Like he said. Just keep the probe wet. seems when they dry out they go bad. My bro likes to drop them in water and then act stupid like he don't know what could of happened. LOL I open the battery compartment and a dribble of water comes out and the thing stays on like 6.6 and won't move.
LOC NAR on probation Reviewed by LOC NAR on probation 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
