7. Maintenance
7.1 Cleaning the probe
Do not attempt to clean the sensors under the filter in any way.CAUTION!
Do not spray anything directly on the probe head, since that may deposit
impurities on the sensors.
You can clean the probe, probe body, and cable by wiping them with a soft, lint-free cloth
moistened with water or a suitable cleaning agent, such as isopropyl alcohol. Do not wipe the
filter: wiping the filter may block its pores and/or deposit residue on the filter. If the filter is
heavily contaminated, replace it.
When cleaning, follow these precautions:
• Avoid touching the filter. If you need to touch the filter, always wear clean gloves (cotton,
rubber or similar material). Keep the filter free of any grease or oil.
• Do not scrape the probe or the probe body.
• Do not immerse the probe or the probe body in liquid to clean them.
• Wipe cleaning agents o the probe, probe body, and the cable after cleaning.
After cleaning the probe, it is recommended to perform a chemical purge.
7.1.1 Chemical tolerance
Avoid exposing the probe to cleaning agents for unnecessarily long periods of
time.
