The pH controller 2001 C is a precision instrument to control 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 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 (not included).
The use of an original Aqua Medic plastic shafted electrode is recommended.
