Unlike disposable pocket-sized pH meters, the miniLab pocket pH meter from Paul N. Gardner contains a virtually unbreakable non-glass silicon chip sensor for fast, stable readings. It is suited for applications such as food and beverage, academic teaching labs, environmental studies, medical, pharmaceutical, agriculture and petrochemical.

The meter uses ion-sensitive field effect transistor sensor technology that contains several proprietary layers deposited on a silicon substrate. The final layer has an affinity for hydrogen ions only. The quantity of hydrogen ions at or near the sensor surface causes an electrical effect that is detected and measured as pH.

The meter features waterproof operation and automatic temperature compensation, and can measure small sample volumes. A replaceable reference electrode can further extend the life of the meter. The sensor stores dry, requiring no storage solutions, and the meter can be cleaned with a toothbrush and a detergent solution.
