🔄 Replaceable electrode

The P110 Pro2 Combo Meter features a replaceable electrode, allowing you to extend the working life of the meter without replacing the entire unit. This supports long-term accuracy and makes ongoing maintenance simple and cost-effective for regular pH, EC and temperature monitoring.

🧪 Electrode care

• Designed for dry storage, so the electrode does not need to be stored in liquid
• Rinse the electrode with water after each use
• Never store the electrode in distilled water
• Do not soak in RO (reverse osmosis), distilled or de-ionised water
• Do not immerse in oil, proteins or suspended solids that leave a layer on the glass bulb
• Avoid sudden temperature changes, such as placing a cold electrode in hot liquid
• Take care not to bump the glass electrode
