pH Universal Plastic Electrode

This Testo pH universal plastic electrode is built for reliable measurements in water and wastewater. It’s designed to handle the rough and tumble of site work, giving you precise readings for applications like cooling towers, boiler water, or process fluids.

When you're out on site, dealing with water quality issues in cooling towers or boilers, you need gear that won't pack it in after a couple of uses. This electrode's robust build means less downtime and more accurate troubleshooting.

Best For

• HVAC service technicians checking water quality
• Facility managers monitoring system health
• Water treatment specialists assessing fluid chemistry
• Plumbing and refrigeration apprentices learning water diagnostics

Compatibility

This electrode is engineered for measurements in both clean water and wastewater applications. It connects via a standard BNC interface, making it compatible with a wide range of common pH meters. If you're running a different model, check fittings and specs before ordering.

Features

• Clog-Resistant Design: Features a single-pore diaphragm that resists clogging, ensuring consistent and precise measurement results.
• Unbreakable Plastic: Built with robust plastic housing, making it highly durable and suitable for demanding work environments.
• Maintenance-Free: Utilises a gel electrolyte, eliminating the need for regular refilling and reducing maintenance hassle.
• Fast Response Times: Provides quick and accurate readings, helping you work more efficiently on the job.
• Standard BNC Interface: Equipped with a fixed 1.2-metre cable and a BNC plug for broad compatibility with pH meters.

Technical Specifications

What's in the Box

• Testo pH universal plastic electrode
• Fixed cable with BNC plug (1.2 m)
• Wetting cap for storage

Using It on the Job

1. Clean the probe tip thoroughly with distilled water before each use to remove any residue.
2. Connect the BNC plug securely to your compatible pH meter, ensuring a tight connection.
3. Calibrate the electrode regularly using known pH buffer solutions (e.g., pH 4, 7, and 10) to maintain accuracy.
4. Dip the probe into the sample liquid, making sure the measurement tip is fully submerged, then allow the reading to stabilise.
5. After use, rinse the probe with distilled water and store it in the wetting cap filled with appropriate storage solution to keep the membrane hydrated.

Limitations & Safety Notes

• Not suitable for highly corrosive liquids or temperatures outside the specified operating range (0 to +60 °C continuous).
• Accurate readings depend on proper and frequent calibration with quality buffer solutions.
• Always handle the probe tip with care; avoid harsh scrubbing or contact with abrasive surfaces.
• Never store the electrode dry; always keep the wetting cap filled with storage solution when not in use.
• Follow Australian standards and Safe Work guidance for any testing involving hazardous materials.

Tradie Pro Tip: Always keep your pH buffers fresh and check their expiry dates. A bad buffer will throw off your calibration, making all your water chemistry readings unreliable for troubleshooting.
