Reef Factory KH Keeper Plus

Reef Factory makes every marine aquarist’s life easier.
KH Keeper Plus meets the highest standards for measuring KH values in your marine aquarium.

KH Keeper Plus has a large laboratory-quality probe and two quiet stepper motors.
It can be controlled in an intuitive and user-friendly manner.

• Improved and quieter stepper pump
• New laboratory quality PH probe
• Larger unit allows easy access to remove and install probe

Measurement accuracy is 0.01dKH
The KH Keeper measures KH value by sampling water directily 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 he 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. 

Advanced controls and simplicity of use
Real user-friendly management and configuration.

Historical measurements are available in the range of 1 day to 1 year.

This device can be controlled easily and conveniently via a phone app.
App is available on the App-Store or Google-Play Store.

Innovative visual indicator of the current KH value
We introduce our simple, interesting and new communication feature.
The KH keeper has an external LED signaling 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.

What is the KH parameter?
This is one of the most important parameters in a marine aquarium.
The KH carbonate hardness (alkalinity) is a measure of the acidic capacity of water and the ability to stabilize the H parameter affecting the corals.
A stable KH value means healthy and colourful corals in the aquarium.
Rapid changes in the KH value can lead to coral health issues. 
Corals from the SPS family, especially acropora, are particularly sensitive to such changes.
