| The pH Controller is a precision instrument for controlling the pH value in aquaria. In combination with a CO²-system and a solenoid valve, the pH can be maintened at a constant level, and the CO² supply to aquatic plants or into a calcium reactor can be controlled. The unit is supplied with a large LED display, and the control range is digitally adjustable from pH 3.5 to 10.5. The pH Controller has a BNC connection for pH electrodes. The pH Controller comes without electrode. suitable electrodes: 368020 368021 Electrode pressurised PG 368034 Elektrode pressurised PG short 368039 |
