Accurate dissolved oxygen measurement in environmental monitoring, industry, and aquaculture: the free handbook
In natural waterways, wastewater treatment plants, or aquaculture – inaccurate dissolved oxygen measurement has direct consequences: compromised water quality, uncontrolled aeration, and risk to fish populations. This free handbook delivers practical knowledge for precise and reliable oxygen measurements – from sensor fundamentals and calibration through quality assurance to the advantages of modern optical measurement technology. Built on over 70 years of expertise in measurement technology.
Dissolved oxygen measurement is business-critical across many fields – in environmental monitoring, industrial process control, and aquaculture, measurement accuracy directly determines the quality of results and the efficiency of processes. Drifting sensors, incorrect calibration, or the wrong measurement technology are the most common causes of unreliable readings.
The oxygen handbook delivers practical knowledge across four core areas:
Dissolved oxygen sensor fundamentals: The different sensor types and how they work – which sensor is right for which application?
Calibration & analytical quality assurance: Methods for sensor calibration and verification for accurate, reproducible, and standards-compliant measurements
Measurement & sources of error: Detailed guidance on measurement methods, typical error sources, and how to prevent them from the start
Optical oxygen measurement: Modern sensor technology with minimal maintenance requirements and maximum precision – operating principle, advantages, and application areas compared to conventional electrochemical sensors
Who should download this handbook? Lab analysts and technicians performing dissolved oxygen measurements in environmental monitoring, water treatment, aquaculture, food and beverage production, or industrial process control.
