Meter Maintenance Products

Electrodes on meters invariably become coated with impurities, reducing their accuracy.

• Suitable for both pH and conductivity meters
• Removes both inorganic and organic contamination
• Restores electrode accuracy and response time
• Helps to maximise electrode life span

The most common cause of pH meter failure is dry storage of the electrode. This causes dehydration of both the glass electrode and wick.

Note:  pH buffers 7.0 or 4.0 or distilled water are not suitable for storing pH electrodes. Electrode storage solutions are carefully structured formulations that do not interfere with the chemical composition of the liquid/gel that is contained within the electrode.

High-precision calibration solution for AquaMaster EC pens, monitors, and meters.

Pro Tip:  Electrical Conductivity (EC) readings are temperature-sensitive. For example, this solution reaches its standard 1413 µS/cm at 25°C.

Helpful Tip: To ensure the longest life and highest accuracy of your calibration fluid, never dip your tester directly into the bottle. Instead, pour a small amount into a clean, dry container for each use. This prevents cross-contamination and ensures future calibrations remain 100% reliable.

This professional - grade fluid is designed for the calibration of Electrical Conductivity (EC) and TDS meters. It provides a consistent reference point to ensure your nutrient strength readings remain reliable and drift-free over time.

pH 7 Buffer Solution.

pH 7 Buffer - the essential starting point for all pH meter calibrations. This neutral buffer provides a consistent baseline, ensuring your digital testers are standardized and ready for reliable daily monitoring.

pH 4 Buffer Solution.

pH 4 Buffer - Specially formulated to provide a stable reference point for the acidic end of the spectrum. This buffer is critical for performing a "two-point" calibration, ensuring your pH pen or probe remains accurate for lower pH readings.

Probe cleaning is one of the most important parts of owning and operating any Bluelab meter. If the probe is contaminated or dirty, it affects the accuracy of the reading displayed.

The probe surface is where the instrument takes the reading of the solution. The information is sent back from the probe to the electronic brain of the instrument.

WARNING - Keep button batteries out of reach of children.
Never allow children to replace button batteries in any device. If swallowed a button battery can cause severe or fatal injuries. If you think batteries may have been swallowed or placed inside any part of the body seek immediate medical attention. The Australian Poisons Information Centre can be contacted 24/7 on 13 11 26. Dispose of used button/coin batteries immediately.
