pH Tester / Buffer Solutions

Extech PH100

We only stock one pH tester now because the waterproof ExStik® pH100 meter has no equals when you consider it's features and price. As far as we can find this is the only flat-electrode tester under $100 that can be used for liquids, semi-solids and solids including pressed cheese. Most other testers in this price range have bulb-type sensors that are hard to use with semi-solids and virtually impossible to use for solid surfaces.

You can review all of it's many features here

Datasheets, manual and videos for the ExStik are here.

Extech PH100

We highly recommend checking meter calibration on a regular basis. While both of these meters can do 3 point calibration, for acidic foods like cheese, beer and wine a 2 point calibration using 4.0 and 7.0 pH buffer solutions should be all you need. Includes (2) 8 oz. bottles: (1) 4.0 pH and (1) 7.0 pH of buffer solutions.
