Be the first on your block to have the complete 3-pack set and let's get calibrating. Whadya say?
What a wonderful way of calibrating a pH meter. When mixed with 250 mL of deionized water as suggested by the manufacturer, (and as seen on TV) you can calibrate to your heart's content. I know that I did and I'm a better man for it. Go Health Metric...all the way!!!

Does the job.
These work fine. Just use distilled/deionized water at the correct temperature and you're good to go.

Great tube o the black stuff.
Recaulked a 55 gallon breeder tank with this. After application, I waited 5 days to put water in it. Not a problem yet. Would order again.
