Milwaukee MW102 pH/Temperature Meter with ATC – Portable, ±0.02 pH, 0.01 Resolution

Milwaukee MW102 pH/Temperature Meter with ATC

Fast, Accurate pH Readings with Automatic Temperature Compensation

The Milwaukee MW102 is a portable, microprocessor-based pH/°C meter designed for quick, repeatable measurements in brewing, meadmaking, water treatment, and aquariums. It features automatic temperature compensation (ATC), two-point automatic calibration (pH 7.01 and 4.01 or 10.01), and high accuracy to ±0.02 pH with 0.01 pH resolution across an extended range of −2.00 to 16.00 pH. The kit includes a lab-grade pH probe and a temperature probe so you can measure with confidence right out of the box.

Why Brewers & Makers Choose the MW102

• Consistent accuracy: ±0.02 pH with 0.01 pH resolution for dialing in mash water, mead must, and rinse/sanitizer checks.
• ATC built in: The meter automatically compensates readings for sample temperature (0–70 °C).
• Simple calibration: Automatic 1- or 2-point calibration using standard buffers (7.01 with 4.01 or 10.01).
• Ready to work: Includes pH electrode (SE220) and temperature probe (MA831R/MA830R), plus long battery life.
• Portable & durable: Handheld design with large LCD for easy readouts on brew day.

Care & Use

• Rinse the probe after readings to prevent cross-contamination.
• Store the probe wet: Use Milwaukee pH Meter Storage Solution (keeps the pH bulb hydrated and ready to read).
• Recalibrate regularly, especially after long storage or big temperature changes.
