pH/ion meters are essential laboratory devices for measuring pH, ORP, and ion concentrations in water and chemical samples. They ensure reliable results in environmental monitoring, food and beverage testing, pharmaceuticals, education, and industrial applications. This category includes both benchtop pH/ion meters, designed for stable and precise laboratory work, and portable pH/ion meters, created for fast field measurements. With advanced digital calibration, clear displays, and durable electrodes, pH/ion meters provide accuracy and repeatability. COLO.Science offers a wide range of pH/ion meters that meet international standards, supporting routine laboratory analysis as well as on-site testing.
