Easy-to-Maintain Pocket pH Meters Store Dry Hach miniLab pocket pH meters feature a virtually unbreakable non-glass silicon chip sensor that gives stable readings in seconds. Unlike traditional, disposable, pocket-sized pH meters, the sensor requires no filling solutions and stores dry, eliminating the need for time-consuming maintenance.
The meter is suited for restrictive or challenging applications, such as food and beverage, academic teaching labs, environmental studies, pharmaceutical, agriculture and petrochemical. The replaceable reference electrode provides meter longevity.
Features include water-resistant operation, automatic temperature compensation, and economical measurement of small sample volumes. Three models are available, providing 1-, 2- or 3-point calibration, temperature display, and pH resolution up to 0.01 pH.
The meter uses ISFET sensor technology that contains several proprietary layers deposited selectively on a silicon chip substrate. The final layer possesses 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.
