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 maintained at a constant level, and the CO2 supply to aquatic plants or into a Calciumreactor 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 direction of adjustment can be set up or down. The pH controller has a BNC connection for pH electrodes.
The use of an original Aqua Medic plastic shafted electrode is recommended and not included.
