Milwaukee SE220 Replacement pH Probe for MW102 – Double-Junction, Gel-Filled, BNC (1 m)

Milwaukee SE220 Replacement pH Probe for MW102

Lab-Grade, Double-Junction Electrode for Accurate, Stable Readings

Restore like-new performance to your Milwaukee MW102 with the SE220 replacement pH probe. This lab-grade, double-junction, gel-filled electrode features a durable resin (ULTEM™) body and a standard BNC connector with a 1 m cable for a quick, drop-in swap. Designed for the MW102 (and MW101), it delivers fast response and reliable stability for brewing, meadmaking, aquariums, and water testing.

Key Benefits

• Double-junction design: Helps resist clogging and sample contamination for more stable readings.
• Gel-filled electrolyte: Low-maintenance—no refilling required.
• Rugged resin body: Chemically resistant ULTEM™ housing stands up to brew-day use.
• Standard BNC (1 m): Plug-and-play with the MW102; no adapter needed.
• Wide working range: Suitable for typical brewing/mead pH and temp conditions.

Specs at a Glance

• Compatibility: Milwaukee MW102 / MW101
• Connection: BNC; Cable: ~1 m
• Construction: Double-junction, gel-filled; resin/ULTEM™ body
• Typical pH range: 0–14 pH; Operating temp: approx. −5 to 70 °C

Care & Use

• Rinse after each reading to prevent carryover and keep the junction clean.
• Store the probe wet: Use Milwaukee pH Meter Storage Solution (keeps the pH bulb hydrated and ready to read).
• Recalibrate regularly (pH 7.01 + 4.01 or 10.01) for best accuracy.

Tip: If your readings drift or won’t stabilize—even after fresh calibration—it’s usually time to replace the electrode.
