Milwaukee pH Probe

pH Probe for BNC Monitors and Controllers

The Milwaukee pH Probe is a lab-grade, gel-filled glass probe for select monitors and controllers. It measures pH in aquarium, service, and general water testing applications where the device accepts a standard BNC pH probe connection.

This probe uses a double-junction design to help reduce clogging and a spherical glass tip to provide more sensing surface area. The gel-filled design means there is no electrolyte to refill, while the 2-meter cable gives extra routing length between the probe location and the monitor or controller.

Key Features:

• Lab-grade glass pH probe for pH measurement.
• Gel-filled electrode does not require electrolyte refilling.
• Double-junction design helps reduce clogging.
• Spherical glass tip provides more sensing surface area.
• BNC connector works with compatible monitors and controllers.
• 2-meter cable gives extra room for routing from the probe to the device.
• Useful as a replacement pH probe for compatible Milwaukee equipment.

Ideal For:

• Aquarium hobbyists replacing a worn pH probe on a compatible monitor or controller.
• Service techs who need a gel-filled pH probe with a 2-meter cable for field testing.
• Users maintaining pH monitoring equipment where a BNC probe connection is required.

Pro Tips:

• Calibrate before use. New and replacement pH probes should be calibrated before they are trusted for aquarium or service readings.
• Keep the glass tip wet. A dry pH probe can respond slowly or fail early. Store it in proper electrode storage solution when not in use.
• Rinse between buffers. Rinse the probe with clean water before moving between calibration solutions. This helps avoid cross-contamination.
• Clean before recalibrating a drifting probe. Buildup on the glass tip can make readings slow or unstable. Clean the probe before assuming it needs replacement.
• Match the connector first. This probe uses a BNC connector. Confirm the monitor or controller accepts BNC pH probes before purchase.
