Description
The Milwaukee MW102 PRO+ is a portable meter that measures pH and temperature with two probes: the SE220 pH electrode and the MA831R stainless steel temperature probe. The temperature probe lets the meter compensate pH readings for temperature automatically, and it also works as a thermometer. The SE220 is a gel-filled, double-junction lab-grade electrode, designed to be low maintenance and to handle difficult samples. Milwaukee aims the meter at growers, brewers and winemakers.

Care
- Keep the pH probe hydrated. Store it with the cap filled with MA9015 storage solution or calibration buffer, the cap tightened and the electrode upright. Use tap water only short term, and never store the probe in distilled or RO water.
- Soak the electrode in MA9016 cleaning solution for about 20 minutes on a regular basis, especially after samples with a lot of organic material.
- Calibrate regularly, and again after cleaning or a long period of storage.
