Care & Maintenance

To ensure long-lasting accuracy, regular maintenance is essential. Protect the sensitive glass bulb and keep the reference junction clean to avoid loss of performance. Extend probe life by following these simple care steps:

Cleaning & Storage

Always clean your pH electrode before and after use, ideally with the Milwaukee Maintenance Kit PH-Main. Store the probe in MA9015 storage solution—never in distilled or RO water—to preserve sensitivity. For best results, fill the probe cap with storage solution or buffer, secure tightly, and store upright.

Calibration

Regular calibration keeps your MW102 meter producing accurate, reliable readings. Calibrate after cleaning or periods of storage to ensure high performance in every test.
