Frequently Asked Questions
1. 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.
2. 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.
3. 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.
4. Are these instruments suitable for field use?
Yes. 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.
5. Can I use these sensors in bioreactors or fermentation tanks?
Absolutely. Specialized electrodes from Conducta and Mettler-Toledo are specifically designed to withstand the rigours of fermentation processes, including high-temperature sterilisation and varying chemical conditions.
