MILWAUKEE PRO+ 2-IN-1 pH & Temperature Meter, pH 0-14, ATC

This 2-IN-1 pH & Temperature Meter is a reliable, fast, and simple-to-use instrument that delivers accurate pH measurements with an accuracy of ±0.02 pH.

It is ideal for brewers, winemakers, growers, and other users with demanding pH testing requirements. This meter is preferred for samples that challenge other pH testers, providing dependable results in various applications.

Accuracy & Calibration

This meter offers two-point automatic calibration for improved accuracy compared to single-point calibration. It includes both a pH probe and a temperature probe, enabling automatic temperature compensation to ensure precise pH readings. The temperature probe can also function as an accurate thermometer.

Durability & Maintenance

Designed for toughness, the rugged MW102 PRO+ withstands knocks and is built for long-term use. It comes with a gel-filled, double junction pH electrode, which is low-maintenance and suitable for challenging samples commonly found in brewing, winemaking, and hydroponics.

Design & Usability

This meter features a large, easy-to-read digital LCD-display, simple push-button operation, and an extended pH range from -2.00 to 16.00. Its lightweight, portable design makes field testing straightforward: simply place the probe in the sample, stir gently, and wait for a stable reading.

Care & Storage

Proper care extends the life of the pH electrode. The glass sensing bulb and reference junction require regular cleaning and hydration. Store the probe in the recommended storage solution (MA9015) and avoid dry storage or using distilled water, which can damage sensitivity.

Cleaning & Calibration Maintenance

Organic residue can affect the sensing bulb and clog the junction. Regular cleaning with Milwaukee's MA9016 solution helps maintain sensitivity. Calibrate frequently, especially after cleaning or long storage, to ensure consistent accuracy.

Supplied Components

The meter includes the SE220 pH electrode, MA831R temperature probe, pH 4.01 and 7.01 buffer solutions (20ml each), a 9V battery, and an instruction manual. Proper maintenance kits are recommended for extended electrode performance.
