Dry Lab grade probes?!

[PolackoTaco]

These are the 4 probes that come with the apex gold, they sat dry for about a year...are all these junk now? Could they just be recalibrated? They were capped and sat in box for about a year now. Thanks for any input, Happy reefing!

The Temp probe and Salinity probes can be dry with no issues. ORP and pH probes need and should be hydrated when not being used. Hanna had an article that staid that you can possibly revive Dry probes by hydrating them in your sump for for a minimum of 2-4 hours but if it was me I would soak the probe for 24hrs and then try to calibrate the pH probe.

I just rehydrated a handheld Milwaukee pH tester, I soaked it overnight in storage solution then tried calibrating. Seems to have worked. It was dry at least a year.
