Maintenance and Procurement Recommendations
Regular Maintenance Steps
- According to the measurement environment, regularly check whether the membrane cap is contaminated or damaged, and replace 51518598 or the COV61- kit if necessary.
- When cleaning the sensor, choose an appropriate cleaning head (71110801 or 71110802) to avoid scratching the membrane surface.
- During calibration, use the 51518599 calibration cap to ensure a stable calibration environment.
- During zero-point verification, use COY8- zero-point gel and operate according to the instructions.
Procurement Notes
- Confirm the compatibility between the sensor model and spare parts, e.g., COS61D and COS61 spare parts are interchangeable.
- Select the protective cap according to the application scenario, e.g., choose 71495130 for fish farm aquaculture.
- When cable extension is required, choose the 51500832 junction box and pay attention to the protection rating.
Correct selection of spare parts can extend sensor life and reduce downtime. It is recommended to confirm the latest order numbers and inventory with the supplier.
