  • Measure pH, conductivity, oxygen with HQD

    After just a short time, the HQD digital electrochemical measuring system has already established itself in practice. Both in the laboratory, with standard electrodes, and in the field, with rugged outdoor electrodes.  On the following pages, users describe their experience with the HQD system. Their experiences show that the system covers a wide range of applications, including direct ...


  • Get the scoop on the newest technology for the measurement of pH

    SENTRON had its 20th birthday in April 2005 and is world wide known as the manufacturer of glass free ISFET (Ion Sensitive Field Effect Transistor) pH systems. During the 20 years we developed and manufactured not only ISFET pH sensors but also pressure sensors in our own silicon chip production facility. This facility for development and manufacturing of solid-state sensors, enables us to ...

  • How can I measure the pH of food?

    Measuring pH in food is a useful indicator of consistency over batches for quality control but can also be used to monitor foods where the pH changes over time – for example in yogurt production, brewing or to test the freshness of foods. Standard pH electrodes will often struggle when used in food samples, as the reference junction becomes blocked the reaction time will get slower and ...

  • Electrolytic denitrification with an ion-exchange membrane in groundwater

    Nitrate contamination of groundwater is an important issue in rural areas. In this study, an electrolytic method for the denitrification of groundwater was investigated in a laboratory reactor. We used an ion-exchange membrane, employing a titanium oxide anode and five kinds of cathode for the investigation. The nitrate removal efficiencies with Cu, Pb, Ti/Ir/Ru, Ti/Ir/Ta, and Zn cathodes were ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...
