Overwintering and testing of probes for the Zodiac Tri saltwater treatment system.

Client:
Hello, I improperly stored my Zodiac Tri saltwater treatment system probes over the winter (without liquid) and now I want to check if they still work. What do I need to do? And if both (red and blue) are defective, what do I need to buy?

Can you send me a photo of your probes? There are multiple versions.

Client:
Will these two products work?

Can you also recommend a good automatic mobile water tester?
