The APERA Instruments PH20 pH meter is an ideal, portable measuring device for determining pH levels in a wide range of applications, such as hydroponics, swimming pools, water treatment, breweries, and water analysis. With this kit, in addition to the meter, you’ll receive a complete calibration and maintenance package that allows you to keep the PH20 accurate and in good working order over the long term.
Why this kit? Regular calibration with fresh buffer solution is crucial for reliable measurements. As a rule of thumb, calibrate at least once a week, and replace any opened buffer solution after about 10–15 calibrations. With the large bottles and the handy CalBox included in this set, you can perform up to 150 calibrations—and save up to 50% on buffer solution compared to open storage.
