pH, DO and Conductivity

METTLER TOLEDO Process Analytics is a leading supplier to end users and system integrators for liquid analytical measurement solutions to control production processes. The Process Analytics division consists of two business units: INGOLD and THORNTON.

 

INGOLD specializes in top-quality solutions for pH, DO, conductivity, turbidity and CO2 for process analytics applications in chemical, pharmaceutical and food & beverage industries.

 

THORNTON is a leader for pure water treatment measurement & control in pharmaceutical, semiconductor and power industries with parameters of conductivity/resistivity, TOC, pH, DO, dissolved ozone and flow.

Transmitters and Meters

Transmitters are an integral part of on-line measurement systems used to monitor and control industrial processes. METTLER TOLEDO offers a comprehensive range of transmitters for pH, DO, conductivity, resistivity, TOC, dissolved ozone, turbidity, CO2 and flow.

pH and Redox Sensors

Monitoring of pH and redox (ORP) is important in many different industrial processes to reduce cost and optimize yield. The requirements of various industry processes are different. For example, in chemical processes sensors must withstand acids or caustic solutions at high temperatures. The electrodes may also require be certification for use in hazardous areas.

O2 / Dissolved Oxygen Sensors

Measurements of dissolved oxygen (DO) in industrial processes serve to control the oxygen concentration, optimize the process and yield. Besides inline measurement the off- or near-line measurement system is often used for control at different sites with a compact portable transmitter/sensor system with data-logger, sampling device and interface to download stored measurement values.

Conductivity / Resistivity Sensors

Conductivity measurements are carried out in industrial processes primarily to obtain information on total ionic concentrations (e.g. dissolved compounds) in aqueous solutions. Widely used applications are water purification, CIP/SIP control and the measurement of concentration levels in solutions.

TOC / Total Organic Carbon Instruments

THORNTON Total Organic Carbon instrumentation provides fast, continuous measurement of ppb-level organic contamination using proven UV oxidation and conductivity measurement technology. It meets pharmaceutical USP <643>, <645> and EP 2.2.44 as well as semiconductor ultrapure water monitoring requirements.

O3 / Dissolved Ozone Sensors

THORNTON dissolved ozone sensors are designed for reliable monitoring in the sanitization of pharmaceutical waters and semiconductor ultrapure water. They give reliable and accurate response and require only infrequent, simple maintenance. They provide stable measurements both in normal ozonation ranges and near zero, after ozone destruction.

Turbidity

Turbidity measurements provide data on the concentration of undissolved, suspended particles present in a liquid phase. The determined particle concentration is used for process monitoring and optimization e.g. to control biomass growth, crystallization and filtration processes or concentration measurement of solid matters in wastewater.

CO2 / Dissolved Carbon Dioxide

Besides pH and dissolved oxygen measurements, reliable monitoring and control of the CO2 partial pressure is important for successful fermentation. The oxidation of carbohydrates to CO2 water results from aerobic respiration. METTLER TOLEDO's new CO2 measuring system is specially designed for in-situ measurement into a bioreactor and therefore "registrates" exactly the same partial pressure as the cell.

Flow Sensors

THORNTON offers a variety of paddlewheel, vortex shedding, and sanitary turbine flow sensors to meet the needs of most pure water treatment applications. Smart flow sensors convey their precalibrated values to the 770MAX instrument for ease of installation and startup. Pulse flow sensors can be used with the 770MAX or M300 instruments.

Cleaning and Calibration Systems

Automated cleaning systems for cleaning of electrodes and sensors during an ongoing process without interruptions is gaining even wider acceptance in the industry. There are clear benefits from the inclusion of cleaning systems in processes with heavily contaminating media and in such which run continuously over longer periods.
