The Dissolved Oxygen (DO) Meters for Labs category includes the instruments, accessories and consumables needed to measure physical, chemical or mechanical properties and convert observations into data that can be compared, documented and acted upon. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately. A practical point for this category is that we offer robust, portable measurement devices from Xylem WTW and Thermo Scientific that are designed for on-site environmental monitoring and are fully waterproof for reliable performance in harsh conditions.
Instrument suitability, calibration and sample preparation all influence whether a result is repeatable and meaningful. This is why laboratories should assess accuracy and resolution, sample type, sensor or fixture compatibility, and calibration requirements before choosing a product, rather than relying only on capacity, appearance or headline specifications.
A sound measurement workflow links representative sampling, suitable sensors or fixtures, calibration or verification, controlled testing and reliable recording of results. When each stage is matched correctly, laboratories in research, quality assurance, manufacturing, environmental, education and service laboratories can work more consistently and manage changeovers, replenishment and maintenance with fewer interruptions. As part of the Analytical Measurement and Testing Equipment range, these products can be selected with the equipment and consumables used before and after this stage.

Frequently Asked Questions
What is the difference between optical and polarographic oxygen sensors?
Optical sensors from brands like Xylem WTW and Mettler-Toledo require less maintenance and no warm-up time compared to traditional polarographic electrodes, making them ideal for high-throughput laboratory and field environments. For dissolved oxygen meters, also check sample type, sensor or fixture compatibility, and calibration requirements so the product fits the complete procedure.
How often should I calibrate my oxygen electrode?
To ensure data integrity, oxygen sensors should be calibrated daily. Most modern instruments from Mettler-Toledo and Lovibond offer easy one- or two-point calibration processes using water-saturated air or zero-oxygen solutions. The final choice should reflect sample type, sensor or fixture compatibility, and calibration requirements, as these points influence day-to-day compatibility and repeatability.
Why is temperature compensation necessary for oxygen measurement?
The solubility of oxygen in water is highly temperature-dependent. Professional devices from Thermo Scientific and Knick include automatic temperature compensation to ensure that your O2 readings are accurate regardless of sample temperature fluctuations. Before ordering, confirm sample type, sensor or fixture compatibility, and calibration requirements and any accessories or consumables needed for routine use.
Can I use these sensors in bioreactors or fermentation tanks?
Specialised electrodes from Conducta and Mettler-Toledo are specifically designed to withstand the rigours of fermentation processes, including high-temperature sterilisation and varying chemical conditions. The final choice should reflect sample type, sensor or fixture compatibility, and calibration requirements, as these points influence day-to-day compatibility and repeatability.
Are these instruments suitable for field use?
We offer robust, portable measurement devices from Xylem WTW and Thermo Scientific that are designed for on-site environmental monitoring and are fully waterproof for reliable performance in harsh conditions. For dissolved oxygen meters, also check sample type, sensor or fixture compatibility, and calibration requirements so the product fits the complete procedure.
