- Modern gel electrode, laboratoriumkwaliteit, 3 m cable length, BNC plug
- Elektrodenhouder for the secure in the aquarium, with lichtweringsscherm against algae
- IJkstation for quick, convenient calibration, saves expensive calibration solution
- Calibration solution pH 4 (50 ml)
- Calibration solution pH 7 (50 ml)
- Distilled water (250 ml)
The reliability of the measurement may, in the course of time go backwards. Periodically the pH-electrode must therefore be replaced to ensure a reliable measurement. Wise to this once every 1.5 years to do. The calibration needs monthly to be performed. This set includes enough liquid for 10 calibrations. Also suitable for saltwater.
