AQUAMASTER COMBO PEN P110 EC-pH-TEMP

Description

Aquamaster Combo Pen P110 EC-pH-Temp is a three-in-one digital measuring instrument from Aquamaster that provides simultaneous or sequential pH, electrical conductivity (EC) and temperature readings from a single, compact combination probe. We have been recommending Aquamaster instruments to UK growers since 2017 as a reliable, well-calibrated monitoring solution for the measurements that matter most in hydroponic and coco growing environments.

Three Critical Measurements in One Instrument

Effective hydroponic nutrient management requires regular measurement of three variables: pH (to verify the nutrient solution is in the correct uptake window), EC (to confirm nutrient concentration is at the correct strength for your crop stage), and temperature (to monitor reservoir conditions that affect both plant root health and the accuracy of pH and EC readings). The Aquamaster P110 delivers all three measurements from a single instrument, eliminating the need to carry and maintain three separate meters for routine reservoir monitoring — a significant practical convenience for busy growers managing multiple reservoirs or who check measurements frequently throughout the day.

The combination electrode in the P110 houses both pH glass bulb and conductivity cell in a single probe body, reducing the number of calibration procedures required for complete monitoring readiness. Automatic temperature compensation (ATC) applies to both pH and EC measurements, ensuring accurate readings across the temperature range encountered in typical grow room environments.

Calibration and Electrode Replacement

Calibrate pH using certified buffer solutions (pH 4.0 and 7.0) and EC using Aquamaster’s calibration standard at appropriate regular intervals. Store the electrode in Aquamaster storage solution when not in use. Replace the combination electrode with the Aquamaster P110 replacement electrode when calibration performance degrades or measurement accuracy becomes unreliable — typically every 12–24 months under regular use.

An excellent all-in-one monitoring instrument for UK hydroponic and coco growers who want professional-quality measurements from a single, practical handheld device.
