Reef Factory KH Keeper Plus With FREE 1L Reagent

Measurement accuracy is 0.01 dKH

The KH keeper measures KH value by sampling water directly from the aquarium. Readings may take place in daily cycles, every 1-12 hours.

Amazing precision and build simplicity

High-quality components and precise control algorithms allow the device to provide extremely accurate KH value readings (with 0.01 accuracy).

If the KH value drops too quickly between the measurements, the device will repeat the test. If the result is confirmed, the user will receive a notification. An aquarist can set a value for the measurement difference. Depending on the user’s preference, the test water can be returned to the aquarium or disposed of.

Maintaining parameters at appropriate levels

The KH keeper measures aquarium water properties and adjusts the liquid dosing processes using a connected dosing pump. This helps keep the KH value at a set level. Soon, this feature will also work with calcium reactors and 3rd party pumps via our Power switcher.

Innovative visual indicator of the current KH value

The KH keeper has an external LED signalling system. The device uses colours to signal the KH value measured in the aquarium. If the KH value is in the safe range, the displayed colour is green. Red  means that the KH value is outside of the safe range. Blue  means that the measurement is in progress.

Actions – interoperability with other Reef Factory devices

Actions make it possible to connect our devices with each other, thus offering a number of new possibilities. Combine KH keeper or KH keeper Plus with Dosing pumps. This will help to keep the KH value at the appropriate level.
