Bought mostly for the CalPod

I bought this kit of the 4 cal, 7 cal, and CalPod mostly for the CalPod. I like that calibration solution can be added for use that can then be sealed off to keep for a short period of time as well as be a nice modular solution holder to make calibration easier. I looked around to just buy the CalPod, which I could only find for ~20 at the cheapest. So, I bought the kit to get some calibration solution and the pod. It comes with some little labels for more than just pH, which is nice because I also wanted to do some EC calibration.

Great calibration kit!!

I bought this particular calibration solution because I have an Apera probe, I'm not really sure it makes a difference who's solution you use but I'll say....I'm glad I did. The quad holder was not something I knew I was getting with this "kit" but how much more convenient could it possibly be?? It also works perfect for the TDS probe, everything I need in one nice little tray!!!

Not as accurate as I’d hoped

The 4.0 fluid needs refreshed often. Won’t calibrate my pH meter to 4.1 except on first calibration of the day.
