Benchtop pH Meters

A pH meter is an electronic measuring probe used for calculating the pH, or the acidity or alkalinity, of a liquid. pH meters are important for consistent and accurate pH measurements of buffers, liquid reagents, media, and chemicals formulated in research labs. pH meters range from handheld devices to complex instruments with computer interfaces and several inputs for indicator and temperature measurements. Benchtop pH meters are available from a number of suppliers in varying price ranges. Most models have a compact design to fit onto any lab benchtop, read pH between 0 and 14, and have user-friendly interfaces. When shopping for a benchtop pH meter, important factors to keep in mind are instrument dimensions, pH range, accuracy, and accessibility.
