🔄 Replaceable electrode

The E50 Pro2 EC Temp 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.

🧪 Electrode care

• Gently clean the electrode with distilled water and dry it off before use and calibration
• Rinse the electrode with water after each use
• If the EC value does not return to 0, dip the electrode in ethyl alcohol and shake gently for 5 to 10 seconds
• Recalibrate after replacing the electrode, and whenever the 30-day calibration indicator disappears

🔧 Replacing the electrode

1. Properly unscrew the sealing ring in the lower part of the meter.
2. Remove the faulty or old electrode by gently pulling it.
3. Carefully place the new electrode with the recess in the correct position, so the connectors connect properly without damaging the meter or electrode.
4. Check that the rubber seal is properly placed.
5. Firmly tighten the sealing ring.
6. Calibrate the meter as described in the user manual.
7. The meter is now ready for use.
