FAQs About Acid-base Controller
Q: How often should I calibrate my Acid-base controller?
A: For optimal performance, calibrate your Acid-base controller at least once a week when in continuous use. In critical applications or if measurements show drift, we recommend calibrating every 2-3 days. Always calibrate when changing electrodes or if the controller has been unused for more than a week.
Q: What maintenance does the Acid-base controller require?
A: Regular maintenance includes electrode cleaning (monthly or as needed), checking cable connections, and verifying calibration. Replace the pH electrode every 12-18 months depending on usage. Keep the controller clean and dry, and ensure proper ventilation around the unit.
Q: Can the Acid-base controller be used with different types of electrodes?
A: Yes, our Acid-base controller is compatible with most standard pH/ORP combination electrodes. For specialized applications (high temperature, viscous solutions, etc.), you may need specific electrodes. Always check the electrode specifications to ensure compatibility with your process conditions.
