The new state of the art innovation from Reef Factory
is set to transform automated control of alkalinity in the Marine Aquarium Industry. Accurate, easy to configure, intuitive to use and with a compact footprint makes this device one of a kind in it’s class.

Measurement accuracy 0,01 dKhKH Keeper measures samples of water directly from the aquarium and tests Alkalinity.
Readings are programmed at maximum every 1 hour – 12 per day.

Amazing precision and simplicity of execution
High-quality components and precise control algorithms determine that the device provides extremely accurate readings to within 0.01 accuracy.

If KH drops too quickly between measurements the device will repeat the test and if the result is confirmed will send a notification to the user. An aquarist can set a value in the measurement difference. The tested watercan be returned to the aquarium or go to waste, depending on user preferences.
Innovative visual indicator for current KH statusWe introduce our simple and great new feature. KH keeper using an outer 'LED' light signallingwill display if the kh parameter is in safe range. Green color means that the measurementis in the safe range, red means that the KH parameter is outside the safe range, the blue color is displayed during the test.

Advanced control and simple to use. Real user-friendly management and configuration.

The device can be controlled very simply via a mobile app, a browser on a laptop or our website.

Historical readingsHistorical readings are available for 1 day to 1 year prior.

Advanced options presented simply

Alerts when KH levelis out of the set range or when KH parameter or decreased to quickly

No need for a central computer
All devices that work with the system are equipped with a Wi-Fi module and connect directly to the system.

Maintaining the parameter on the appropriate level
KH Keeper measures 'aquarium' water from aquarium and will make corrections using the connected dosing pump. This function will allow the precise control of the KH parameter to the level determined. It will soon work also with calcium reactors and 3rd party pumps via Power switcher.
