Mettler Toledo analytical sensors are laboratory sensors for pH, conductivity, ion concentration, dissolved oxygen and ORP. Routine to highly-specialized pH electrodes and probes provide accurate readings for a wide range of laboratory and field applications. Variety offerings include built-in temperature probes, low-maintenance options, and our Intelligent Sensor Management (ISM®) to enhance data security and easy handling.
Laboratory pH Sensors
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.
Laboratory Conductivity Sensors
A conductivity sensor measures the ionic content of an aqueous solution, using the property of electrical conductivity. Determining conductivity is essential for many labs to ensure the desired quality of a product, including those involved in pharmaceutical research, food & beverage quality control, water analysis, or environmental monitoring. Mettler Toledo manufactures reliable conductivity electrodes and probes that provide accurate readings in low and high conductivity solutions for a wide range of laboratory and field applications.
Ion-selective electrodes (ISE) are modern analytical tools for fast and accurate ion activity determination in a wide range of lab and field applications. The effective determination of ionic concentrations is paramount in industries such as biomedical, environmental monitoring or food processing. Together with a suitable ion meter or titrator, Mettler Toledo offers complete solutions to cover all ion measurement needs such as fluoride, chloride, sodium, potassium, calcium, nitrate, and more.
Dissolved Oxygen Electrode
A dissolved oxygen electrode determines how much oxygen is dissolved in a solution. As an indicator of quality, knowing the amount of free, non-compound oxygen in a product is important for many types of labs, including those involved in pharmaceutical research, food & beverage quality control, or environmental monitoring. Mettler Toledo manufactures optical, polarographic, and galvanic electrodes for accurate DO determinations in a wide range of laboratory and field applications.
Laboratory ORP Sensors
Oxidation-Reduction Potential (ORP) or redox sensors measure the ability of a solution to act as an oxidizing or reducing agent. The ionic potential information an ORP probe obtains is critical for various industrial applications, such as checking drinking water purity, monitoring the anaerobic activity of wastewater, and ensuring consistency in food production processes, such as baking. Mettler Toledo manufactures a versatile portfolio of high-quality ORP electrodes for lab and field applications. ORP sensors with silver, platinum, or gold rings offer the possibility to measure redox potentials in media with various chemical properties.
