Dissolved Oxygen Meters for Laboratory, Water Quality & Industrial Testing

Techris Systems supplies dissolved oxygen (DO) meters in Ireland for laboratory analysis, water quality testing, research and development, and industrial process monitoring.


Dissolved oxygen meters measure the amount of oxygen present in a liquid. Depending on the instrument and application, measurements can help assess water quality, monitor treatment processes and support routine laboratory testing.


Our range includes portable dissolved oxygen meters for field and production use, as well as advanced instruments for laboratory measurements. Options include optical and polarographic sensor technologies, with features varying by model.


Whether you need to measure dissolved oxygen in water, investigate process conditions or select an instrument for routine quality control, Techris Systems can help you choose a suitable meter for your application.

Applications for Dissolved Oxygen Measurement

Dissolved oxygen measurements are used in a range of laboratory, water-quality and industrial applications. The most suitable instrument depends on the sample, measurement range and testing procedure.


  • Laboratory analysis: Measure dissolved oxygen in suitable water samples for routine testing and research.
  • Pharmaceutical and chemical processes: Monitor dissolved oxygen where it is a relevant process parameter and the selected instrument meets the requirements of the application.
  • Water treatment and wastewater: Assess oxygen levels during water-quality checks and process monitoring.
  • Industrial quality control: Support testing of water and suitable process liquids.
  • Environmental monitoring: Measure dissolved oxygen in rivers, lakes and other aquatic environments.
  • Aquaculture: Monitor oxygen levels in fish-farming and aquatic systems.



Techris Systems can help you identify a suitable dissolved oxygen meter based on your measurement requirements and intended application.

Choosing a Dissolved Oxygen Meter

When selecting a dissolved oxygen meter, consider the type of sample, required measurement range, testing environment and level of documentation needed.


Important features to compare include:


  • Sensor technology: Optical and polarographic probes operate differently; choose according to your testing needs.
  • Measurement units: Depending on the model, readings may be displayed as mg/L, ppm or percentage saturation.
  • Temperature compensation: Check how the instrument accounts for sample temperature.
  • Salinity and pressure compensation: These features may be important for particular water samples and measurement conditions.
  • Portability and probe cable length: Consider whether measurements will be taken at a bench, on a production site or in the field.
  • Data storage and documentation: If records are required, check the model’s data-storage and export capabilities.

FAQs

  • What is a dissolved oxygen meter used for?

    A pH meter measures how acidic or alkaline a sample is. It is used in food production, laboratory testing, water analysis, brewing, agriculture and industrial processes.


  • What is the difference between an optical and a polarographic dissolved oxygen meter?


  • Do pH meters need calibration?

    Yes. Regular calibration is important for maintaining confidence in pH measurement accuracy. Calibration requirements depend on the instrument, application and quality-control procedures.


  • Can dissolved oxygen meters be used in laboratories?




  • Can I buy dissolved oxygen meters in Ireland?



  • How do I choose the right dissolved oxygen meter?

    Consider the sample type, measurement range, required accuracy, sensor technology, probe configuration and whether you need data storage or specific supporting documentation. Techris Systems can help you compare suitable models.
