  • Great design, perfect ph.
Style: pH 7/4/10 (16 oz) + CalPod
Works as intended for my ph meter. Great design for solution storage and ph meter holder.

  • This is the real deal.
Style: pH 7/4/10 (16 oz) + CalPod
After buying some off brand calibration solution my ph20 meter said my tap water was at 6.7 ph. I know my tap water is 7.2 - 7.3. I bought this kit with the 3 solutions the 3m kcl, and the cal box. Now my meter is reading correctly.

  • Perfect for pH probe calibration.
Style: pH 7/4/10 (16 oz) + CalPod
It's accurate, a good value for the money, and there's enough of it to last a while. I'm impressed.

  • Great PH calibration set
Style: pH 7/4/10 (16 oz) + CalPod
This is a great set for calibrating your PH meters. It came with 3 buffers, storage solution and a solution storage case (CalBox). I really like the CalBox. It makes it so much easier to calibrate my PH meter. Juggling small bottles is no fun. I also used one of the complements for distilled water. The only complaint I have is the CalBox lids aren’t water tight. If you do happen to turn it over, some will leak out. Its not a fatal flaw, just annoying. I was hoping to be able to drain one of the compartments as needed but its pretty much all or none. Otherwise I am very happy with the set! ... show more

  • This is lab grade kit!
Style: pH 7/4/10 (16 oz) + CalPod
I purchased this without knowing what was in the kit when I was buying my probe. This is a kit of 4 bottle of calibration solutions and a little stand for the solutions. Not something someone at home needs. I returned and will be buying just the 2 solutions that came with my probe when needed. Which should be in a year or 2. ... show more

  • Did not include what was advertised
Style: pH 7/4/10 (16 oz) + CalPod
I can’t speak to how well the solutions work so this review is unfair in that sense. But I ordered a kit that should have everything I needed but it was missing the storage solution. The box was sealed with a label that had a photo of as well as listed the contents. Even though it is pictured and listed the storage solution wasn’t in the box. Because it is such a hassle to return it I’ll just keep it and keep testing my ph with api drops. Wish I would have read farther into the reviews and I would have seen I’m not the only person that has had this problem. ... show more
