It looks like it has more options than the Basic. BYO reccomends the Basic for their online class so might be better.

I'm getting into water chemistry to improve my beers. The kit includes everything I need for 50+ water tests and includes a PH meter (which I was looking to buy anyway).

Does this kit come with ph meter storage solution?
Chris Herb on Nov 5, 2018
BEST ANSWER: It comes with storage solution pills that you dissolve in distilled water. Buy a gallon of distilled. You will need it for mixing that and the calibration solutions.
Are probes on the pH meter replaceable?
Tracy Crenshaw on Jun 20, 2018
BEST ANSWER: The one that came with mine had a replaceable probe and I have since replaced it with no problems.
What temperature is the pH probe good to? A lot of pH meters are good to 125F, some are good up to 212F.
Brad Probert on Aug 15, 2018
BEST ANSWER: The operating temperature of the ph meter recommended by the manufacturer is 32 to 122 ° F (0 to 50 ° C), the important thing is always gauge at the sample temperature. According to manufacturer the temperature range of the meter is from 23 to 194 ° F (-5 to 90 ° C)

Excellent kit, ample testing materials, but dried out pH electrode
The kit is well-packaged and bottles are sealed. It includes ample tablets and solutions to last for dozens of uses. Perfect for me who moves frequently and brews about 4 times a year. The manuals were a bit rubbed and a cover was torn (like it may have been reused or possibly caught in the zipper on the case).
The pH meter arrived completely dry. The electrode sponge was bone dry. I was concerned that the electrode would work reliably. After calibration, the readings were a bit sporadic and it took at least 30 seconds to settle on a pH value. The readings were in the ballpark (+/- 0.25) but not as accurate as it should be for a $100 pH meter. However, the next day I recalibrated, and it worked much better (faster convergence to a reading). So today I took this into the university chemistry laboratory where I work and validated the readings with another instrument and several buffers (4, 7, 10 pH +/- 0.02). It worked fine. So I’m happy with this kit, but beware of the pH probe if it dry. Soak it for a day or two before making measurements.

Simple and effective
This kit is really well put together, everything has its place and is clearly labeled. The instructions are simple and guide you through the tests step by step. I was wondering if I'd have difficulty determining when the colors changed, but it's pretty obvious.

Not sure if this is worth it or just get a Ward Labs Test Kit
The test kit overall is decent. It does what it is suppose to and the directions are pretty clear. The sulfate test is VERY subjective and in my opinion doesn't really work. Although, maybe my sulfates are just that low. So, the kit lost a star for that reason.

That being said, I opted the the kit with the pH meter. My meter was defective and MOREBEER worked with the vendor to obtain me a replacement quickly and easily!!!!

Dial in your brewing!
This works great. Easy to test. I have well water so mineral content can fluctuate. This is easy enough to test before each brew day. I got the set that comes with the PH meter. The meter is much better than the cheaper one I used to have. The probe is replaceable so you don’t have to buy a new meter when the probe goes and it will. Very simple instructions for the water testing and the ph meter.
