A laboratory pH sensor is used to determine the alkalinity or acidity of a sample both in the lab and in the field. METTLER TOLEDO offers reliable pH electrodes and probes that provide accurate readings for a wide range of applications in industries such as pharma, biotechnology, F&B, or chemical. We have a broad portfolio that includes built-in temperature probes and low-maintenance options, and our Intelligent Sensor Management (ISM®) enhances data security and makes handling easy.
