pH Monitor with LED alarm. The SMS120 pH monitor allows you to continuously monitor pH values directly in your aquarium. Features include: user selectable set point, visual LED alarm when values go above the set point and manual calibration. Powered by a 12VDC adapter all smart monitors are supplied with a clog-resistant pH electrode.

pH controller with standard plug socket support, .1 resolution, includes AC adapter. The SMS122 pH controller enables you to automate your dosing of CO2 and makes sure that the plants in your aquarium are always healthy. Simply plug in the solenoid valve to the plug socket supplied.

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 set point. Includes Platinum ORP electrode with 2m cable.

Monitor and control pH and ORP levels with 1 single unit! Dual set points - for pH (5.5 to 9.5) and for ORP (0 - 600 mV) - adjustable with knobs. Simply attach 2 solenoid valves or pumps to the plug sockets supplied to dose CO2 and ozone as required! Visual LED alarm and includes pH electrode and platinum ORP electrode.
