  • Genuine OEM Match:​ Ensures chemical compatibility and measurement traceability with COS31/COS41 sensors.

  • Standard vs. Fast Response:​ This kit (COY31-Z) fits standard-response sensors; fast-response COS31-S requires COY31-S-Z.

  • Extended Sensor Life:​ Regular membrane/electrolyte renewal restores sensor performance and avoids premature sensor replacement.


Applications

  • Wastewater Aeration Basins:​ Routine servicing of DO probes in activated sludge process control.

  • Environmental Monitoring:​ Maintenance of sensors deployed in rivers, lakes, or coastal waters.

  • Aquaculture:​ Keeping DO probes in fish tanks and raceways within spec.

  • Industrial Effluent:​ Scheduled preventive maintenance in discharge monitoring stations.


Note: Membrane cap COY31-WP is also available separately (Order No. typically 51506684). Always verify sensor model (COS31/COS41) and response type before ordering.
