Specifications
Ideal for the Aquarium market, the SMS122 pH controller
enables you to automate your dosing of CO
2
and makes
sure that the plants of your aquarium are always healthy.
Simply plug in the solenoid valve to the plug socket sup-
plied.
Every aquarium needs individual attention. This is why the
SMS510 has a user selectable set point for the ORP
(0 to 600 mV).
Simply plug the ozone generator into the controller’s
power plug and it will dose until the mV set point is
reached.
It will automatically switch on again if the ORP falls below
the adjusted point.
SMS125 has dual set points adjustable with knobs: for pH
(4 to 8 pH) and for ORP (-200 to 600 mV).
Simply attach 2 solenoid valves or pumps to the plug
sockets supplied to dose CO
2
and ozone as required!
Perfect and ideal where 24-hours maintaining is required.
