ECO-209 pH meter

ADWA ECO-209: a pH monitor with an immersion electrode for continuous pH monitoring

The ECO-209 pH meter is a continuous pH monitor for aquariums, pools, hydroponic systems and other uses where you want a constant display of the pH value. You immerse the electrode about 10 cm deep into the liquid and read the current pH on the display all the time. According to the manufacturer's description it is made mainly for use in hydroponic systems.

The set includes the ECO-209 pH monitor with an electrode, a 12 V DC adapter and calibration liquids of pH 4.01 (20 mL), pH 7.01 (20 mL) and 12880 µS/cm.

Use: ECO-209 pH meter

Who is it for

Choose it when you do not want to dip a handheld tester every time, but need a pH monitor that stays connected. For occasional measuring see the pocket AD-12 pH meter or the cheaper AD-11 pH meter. If you also measure ORP, the pH/ORP meter AD14 is suitable.

Maintenance: ECO-209 pH meter

Storing and cleaning the electrode

Calibrate and check the electrode regularly. According to ADWA's instructions for pH electrodes, keep it moist in a storage solution, never in distilled water. Clean it occasionally with a pH electrode cleaning solution and then recalibrate.
