Healthy fish thanks to an ideal pH value
The acidity defines the pH value of the water. It needs to be constantly checked and adjusted as necessary to maintain the health of the fish and plants. The correct pH value depends on the fish stock of the aquarium. The wrong pH value can cause stress and disease.

Easy to connect
Connect the pH electrode with the BNC connection to its corresponding measuring and control device. - RELIABLE: The electrode has been individually tested and documented and needs to be replaced after about 2 years. It comes with a large protective cap, filled with storage solution.

pH electrodes:
Every pH control or measuring device and also the JBL pH-CO2 control unit (JBL PROFLORA pH-CONTROL) requires a pH electrode (JBL PROFLORA CO2 SENSOR) to measure the pH value of the water. pH electrodes age with time and must be replaced about every 2 years. Every 30-45 days the pH electrode needs to be calibrated so that it continues to show accurate values. During calibration, the functionality of the electrode is also checked so that you know when a new electrode is needed. The pH electrodes do not like the addition of medication in the water and should be placed in a glass of aquarium water during treatments. pH electrodes should not be stored in distilled water but in a potassium chloride solution (KCl, a JBL storage solution).

Positioning the pH electrode in the aquarium: attach the pH electrode with the enclosed suction cups to an ideally dark area in the aquarium with little current. Electrodes easily become algae-ridden in very bright locations.

Key Features:

• Robust quality electrode for the JBL CO2 Control unit and other pH measuring and control devices with BNC connection, incl. liquid for calibration and storage of pH sensors
• Simple connection: connect the electrode via BNC connector to the respective measuring or control device (not supplied)
• Large protective cap filled with storage solution, plastic shaft and gel filling, suitable for many systems with BNC connector
• Individually tested with an individual test report
• Package contents: pH electrode, 2 m cable, 2 suction holders for attachment, 3 cuvettes, 50 ml cylinders: storage solution, distilled water, calibration liquids pH 7.0 and 4.0
