## Questions & Answers

**Q: How do i use this? i think my hanna orp meter was dry for too long.**
A: If you haven't soaked it in the storage solution definitely do that. Fill the meters cap with the solution and place it in there. You always want to have the solution in the cap

**Q: Do the bottles have a lot number and expiration date imprinted?**
A: Yes, they have an expiration date printed- and amazon ask for them before they are allowed to be sent into the fba program.

**Q: What ph does this solution keep a ph/ec/tds meter's electrodes?  should one be able to use their meter, immediately from the storage solution?**
A: The ph storage solution is right around a 4 ph. I always re-calibrate with 4.01 & 7.01 after removing from the storage solution.

## Customer Reviews

### ⭐⭐⭐⭐⭐ it works
*by C***N on November 8, 2011*

Use it to store any of your pH or ORP electrode probes. It works, not much else to say.Most electrodes come with some type of sponge soaked with this solution but peopledon't replace it when they store the electrode. I use this for the sponge that comes withthe pH probe electrode on my Hanna portable pH probe. Keeps yours electrode in good working shape.

### ⭐⭐⭐⭐⭐ The storage solution is the storage solution
*by L***S on August 11, 2014*

I've ordered this before for use on my pH meter - they're expensive and well worth taking care of - and I've reordered it at least once, since, and will again, I'm sure. Excellent product!

### ⭐⭐⭐⭐ Works fine. Casual user and this will last several years ...
