Description
Aquamaster P110 Combo Replacement Electrode is the replacement combination electrode for the Aquamaster Combo Pen P110, which measures pH, EC and temperature in a single instrument. We have been supplying Aquamaster measurement equipment and accessories to UK growers since 2017 as a reliable, precision monitoring solution for the hydroponic and soil growers who depend on accurate measurements for nutrient management throughout every growing cycle.
Maintaining Measurement Accuracy Over Time
Combination electrodes — which house both pH glass bulb and conductivity cell in a single probe body — have a finite service life that typically ranges from 12 to 24 months depending on maintenance quality and frequency of use. The conductivity and pH measurement elements age independently but simultaneously in a combination probe, meaning both measurements benefit from a fresh electrode when replacement is due. Signs that replacement is needed include slow pH stabilisation, drifting calibration, EC readings that diverge from known-standard solutions, or visible damage to the probe tip.
Regular replacement at the appropriate interval is significantly more cost-effective than purchasing a new instrument and ensures the measurement accuracy that effective nutrient management depends on. The Aquamaster P110 replacement electrode is a direct factory-specified fit for the P110 instrument body, restoring the meter to full factory specification upon installation and calibration.
Replacement and Initial Calibration
Follow the Aquamaster P110 manual for electrode replacement procedure. After fitting the new electrode, allow it to hydrate in storage solution for the period recommended by Aquamaster before performing initial calibration. Calibrate using certified pH 4.0 and 7.0 buffer solutions and EC calibration standard at the appropriate concentration for your meter’s EC range. Store the new electrode in Aquamaster storage solution when not in active use to maximise service life.
Pairs with Aquamaster calibration buffer solutions (pH 4.0 and 7.0), EC calibration standard and electrode storage solution for a complete meter maintenance kit.
