Gas Analytics

In situ oxygen gas sensors measure where it matters – directly in the process. In our portfolio of amperometric and cutting-edge tunable diode laser (TDL) oxygen sensors, you will find a solution for your oxidation and explosion protection applications. For industries ranging from (Petro)Chemical to Food & Beverage to Pharmaceutical, amperometric and TDL oxygen gas analyzers offer reliability, ease of maintenance, and low cost of ownership.

In industrial processes different parameter measurement systems are mounted to optimize and control the process. Housings are a very important part of the whole system as they allow to insert the sensors into the media at a specific place in the process (pipe, vessel or basin).

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.

PH 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 are also certified for use in ATEX Hazardous Areas.

Turbidity Sensors

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.
