Milwaukee pH Meter - Help!

Just change the KCL in the electrode...that should fix it. If it doesn't then probe membrane is shot

KCL? Potassium chloride? lol I have no idea what that is. How do I do that? I'll try a Google search...

Most likely the probe is shot if it keeps drifting after recalibration. For the Milwaukee unit buying a new probe ($50 according to J&L) is almost as much as buying a brand new pH meter ($62).

The next pH meter I get will one with a probe which you can replace with a standard generic pH probe with a BNC connection (you can find them for about $20-$25) when it dies.

Ya, I contacted J&L about replacing the tip. Not worth it. I will probably just end up buying a Pinpoint pH monitor.

Potassium Chloride is the solution they use inside the electrodes.
