ph probe dried out

[brotherd]

My Pinpoint ph probe dried out in storage.Is it junk now?

It may be fine. I would get some calibration fluids, do a calibration and then put the calibrated probe in one of the packets and see if it reads what it should be. The calibration fluids are really cheap.

Thanks. I'll give it a shot.

Soak it in pH 7.0 calibration fluid for 2 or 3 hours turned off first. Then go through the steps to calibrate using a new packet of pH 7.0 and pH 10.0. If it calibrates, then you're golden. Check calibration after by dipping back into the packets and see if they read accordingly. Make sure to rinse in RO between packets.

Great success! Even tried it in ph 4 and all is good.Last night at lights out the tank was at 8.22. this am its at 7.84....

Awesome. That's a big swing though. Are you going to do something about it or leave it?
