Milwaukee pH Meter - Help!

[mark]

not normal, probe failing, battery ok?

I leave my probe in a container that reactor effluent drips into. When I turn the meter on, see the numbers bounce a bit but become steady after about 2 second. If I move my probe into the sump, it locks into the tanks pH in about 15 second with me not moving the probe around.

Using a Milwaukee meter, Aqua-digital probe.

Mine never bounces around. It hits a number, and slowly falls. I was thinking the probe might be dying...not sure about the battery.

If you put yours in a cup of saltwater outside the tank, and let it sit, when does it stop moving?

You might want to start a new thread, you will get more replies that way.

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.
