AQUA MASTER TOOLS P110 Pro pH, EC & Temp Electrode
The AQUA MASTER TOOLS P110 Pro pH, EC & Temp Electrode is a genuine replacement electrode for the AQUA MASTER TOOLS P110 Pro Combo Pen. It restores accurate pH, EC and temperature readings by replacing just the electrode rather than the entire meter. When attached to the meter, the electrode is IP67 waterproof.
⭐ Key features
- Replaceable pH, EC and temperature electrode
- Suitable for the AQUA MASTER TOOLS P110 Pro2 Combo Pen
- IP67 waterproof when attached to the meter
- Extends the working life of your meter
💧 Before first use
Soak the electrode in tap water for at least 12 hours before use. This helps dissolve the salts and ensures the electrode is properly activated. Dried salts around the pH electrode are normal and not a cause for concern.
🔄 Replacing the electrode
- Properly unscrew the sealing ring in the lower part of the meter.
- Remove the faulty or old electrode by gently pulling it.
- Carefully place the new electrode with the recess in the correct position, so the connectors connect properly without damaging the meter or electrode.
- Check that the rubber seal is properly placed.
- Firmly tighten the sealing ring.
- Calibrate the meter as described in the user manual.
- The meter is now ready for use.
🧪 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
