Frequently Asked Questions
1. When should I replace my oxygen sensor membrane heads?
Membrane heads, such as those for the StirrOx® G, should be replaced if you notice slow response times, unstable readings, or if the membrane appears physically damaged or fouled.
2. What is the advantage of using a flow-through vessel?
Flow-through vessels like the D 3Sen or D 201 allow for dissolved oxygen measurement in a closed system, preventing atmospheric oxygen contamination and providing a stable environment for the sensor.
3. Does the Xylem WTW FDO 925 require calibration?
While optical sensors are highly stable, periodic verification and calibration using a vessel like the OxiCal-SL are recommended to maintain laboratory-grade accuracy.
4. Are these accessories compatible with all DO meters?
Most accessories and sensors listed are designed for specific manufacturer ecosystems, such as Xylem WTW or Mettler-Toledo; always check the manufacturer part numbers for compatibility with your specific base unit.
