Selection and Maintenance Recommendations
How to Select Spare Parts
- Confirm the sensor model: COS81D or COS81E.
- Select COV81 maintenance kit or COY8 zero-point gel according to maintenance needs.
- Refer to the order number table and select the complete order number with the corresponding suffix.
Maintenance Cycle
- The optical cap is recommended to be replaced every 6-12 months, depending on operating conditions.
- Inspect the O-ring during each maintenance; replace immediately if aged or damaged.
- Check the expiration date of the zero-point gel before each calibration; do not use if expired.
Correct selection of spare parts can extend sensor life and ensure measurement accuracy.It is recommended to purchase from official channels to avoid performance degradation caused by compatible parts.
