Tunze measuring instruments have been specially developed for use in aquaria. The meters and electrodes operate at a very high degree of accuracy, are robust and are comparable with laboratory grade instruments in quality and reliability.

Tunze pH / CO2 Control Set 7074/2 is a programmable pH controller with an LCD display. This control set consists of the pH Controller (7070/2), a CO2 control valve / solenoid (7074.110) and power supply unit (5012.010).

The control set can be used to regulate the delivery of CO2 into aquaria. The supply of CO2 is fed from the storage bottle, through the CO2 control valve / solenoid (7074.110) and then into the aquarium via the CO2 diffuser. The rate of CO2 delivery is controlled by the CO2 control valve / solenoid (7074.110), which is opened or closed by the pH controller, depending on the pH of the water measured by the pH meter. The point at which the CO2 is switched on and off is preset on the pH meter by the user at any point between pH 5 - 9.

In freshwater aquaria, where plants are being grown, the controller can be preset to a pH value below which the CO2 dosing can be switched off. This prevents the pH falling too low due to too much CO2 being dissolved in the aquarium water, especially at night when photosynthesis stops. In marine aquaria, the Tunze pH / CO2 Control Set 7074/2 is frequently used in conjunction with a suitable calcium reactor. It can control the CO2 supply to the calcium reactor and prevent the water leaving the reactor from having excess CO2 than would cause a fall in the pH of the aquarium water. This also increases the efficiency of CO2 usage.
