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.

Manufacturer-Warrantied Brands
Some of the brands we carry are covered by the manufacturer's own warranty rather than a CoralVue warranty. Warranty terms vary by brand — we recommend visiting the manufacturer's official website or contacting them directly for current coverage details and the claims process.

Instructions:
- Remove the probe from its packaging and inspect the glass tip, cable, and connector for damage.
- Connect the BNC connector to the compatible monitor or controller.
- Rinse the probe tip with clean water before calibration.
- Calibrate the probe using the buffer values required by the monitor or controller.
- Rinse the probe between each calibration solution to avoid cross-contamination.
- Place the probe tip into the sample or monitoring location after calibration is complete.
- Allow the reading to stabilize before making decisions based on the pH value.
- Keep the probe tip wet during use and storage.
- Clean the probe when readings become slow, unstable, or difficult to calibrate.
- Store the probe in proper electrode storage solution when it is not in use.
