Each Specialized pH Tester is equipped with everything you need for successful testing right out of the box including buffers, cleaning, and storage solution.
Specialized Cleaning Care
pH electrodes become dirty with use and can produce inaccurate results. Each tester comes with a specialized pH cleaning solution designed to eliminate residues and maximize the efficiency of your electrode.
The Right Buffers
When performing a pH calibration, it is important that the correct buffers are used. We include buffers to get you going. The single-use sachets are individually sealed so you use fresh buffer each time you calibrate.
Storage Solution
Proper storage of your electrode will ensure reliable measurements and a long electrode life. Our storage solution is specially formulated to keep the pH glass hydrated while minimizing organic growth.
