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.

Works and seems to be an accurate reference material.
My only gripe is that it smells very strongly of wintergreen. Your instrument will smell of wintergreen even after you rinse it, meaning something is left coating your sensitive and highly expensive ph meter. This doesn't seem to impact performance however. And other reference materials are not as fairly priced, so its a good buy. My bottles arrived leak-free and were packaged well. I would reccomend this product as long as you can stand the minty-fresh smell that hangs around on your instrument for several days. Atleast it smells fresh i guess!

Easy directions. Came well secured.
Love these. A little goes a long way. Instructions are clear and they last long. They came well secured. I love that. I definitely will purchase again.

Establish confidence and validate your measurements... it's good insurance
Ordered the calibration kit with the storage solution. The kit was shipped promptly, packed well and arrived in a couple days. Having the different colors in the liquids does make it easier to work with and less chance of making errors. There's plenty of solution for my needs to maintain a commercial pool monitoring system. The storage solution is also being used for my ORP probe. The pH 7.0 reference can also be used to validate my Taylor daily pool water test kit. The acidic solution came with an extra foil seal to prevent leakage... good idea. This order was for two, so I'm giving the other away as a "gift" to a friend in the industry.
