Detailed Description of Spare Parts
Electrode Protective Cap (Order Number: 71538217)
- 20 pieces per pack, used for pH sensor electrode protection.
- Prevents electrodes from drying out or contamination during storage or transportation.
- Suitable for CPSxx series sensors.
ORP Calibration Solution (Order Number: CPY3-)
- Used for calibration of ORP (oxidation-reduction potential) electrodes.
- Technical grade solution to ensure measurement accuracy.
- Recommended to replace regularly to avoid contamination.
KCl Electrolyte (Order Number: CPY4-)
- Specially designed for liquid-filled electrodes.
- Maintains the reference electrode junction unobstructed.
- Replenishing electrolyte can extend electrode life.
Sensor Clip (Order Number: 71038228)
- 100 pieces per set, with printable labels.
- Used for corresponding identification between sensors and measurement loops.
- Facilitates on-site installation and maintenance management.
pH Buffer Solution (Order Number: CPY20-)
- High-quality buffer solution, traceable to PTB and NIST standard reference materials.
- Comes with a calibration certificate to ensure calibration traceability.
- Suitable for precise calibration of pH electrodes.
Selection and Ordering Notes
- Confirm sensor model: The CPS76D series requires matching CPSxx protective caps.
- Choose electrolyte based on electrode type: Use CPY4- for liquid-filled electrodes.
- Select calibration solution as needed: Use CPY3- for ORP calibration and CPY20- for pH calibration.
- Purchase sensor clips in bulk: 71038228 contains 100 pieces, suitable for multi-point projects.
Maintenance Recommendations
- Regularly check whether the electrode protective caps are intact and replace them in time.
- ORP and pH calibration solutions should be used within their shelf life to avoid cross-contamination.
- Replenish electrolyte when the level is below 1/3.
- Sensor clip labels should be clear to facilitate loop correspondence.
Proper selection of CPS76D spare parts can significantly improve measurement reliability and reduce downtime. It is recommended to confirm the latest order numbers and inventory with the official supplier.
