NA CONTROL TIMER II – a renewed model of NA Control Timer with a sophisticated design with aluminum exterior, is an essential need for daily aquarium maintenance. Same as the conventional NA Control Timer, a loaded solenoid valve is opened to supply CO₂ in conjunction with the lighting circuit when activated. As the light is turned off, aeration will be started. It makes timer set-up easier than the previous model, and also allows you to switch the frequency.
NA CONTROL TIMER II allows you to switch frequency between 50 Hz and 60 Hz, and the setting of ON and OFF time becomes even easier.
* NA Control Timer Ⅱ can be concurrently connected with 2 Solar RGBs.
* NA Control Timer Ⅱ is compatible with only one unit of Solar I or Grand Solar.
