Maintenance
Clean the probe
Clean the probe when:
• Drifting/inaccurate readings occur as a result of contamination on the sensing
element or improper storage conditions.
• Slow response time occurs as a result of contamination on the sensing element.
• The slope is out of range as a result of contamination on the sensing element.
For general contaminants, complete the following steps.
1. Rinse the probe with deionized water. Blot dry with a lint-free cloth. Do not touch the
tip of the probe.
2. If harsh contaminants are attached to the probe, polish the probe tip with a soft cloth
or cotton swab to remove the contaminants.
3. Soak for 30 minutes in 100 mg/L Ammonium standard solution.
Storage
The probe can be stored dry. To protect the sensing element, rinse with DI water and blot
dry with a lint-free cloth. Install the sensor protection cap.
Note: The probe must be conditioned after long-term storage. Refer to Preparation for use
on page 2.
