KH keeper

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.

Minimalist design
Compact dimension

Measurement accuracy 0,01 dKh

KH 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 water  can be returned to the aquarium or go to waste,  depending on user preferences.

Innovative visual indicator  for current KH status

We introduce our simple and great new feature. KH keeper using an outer 'LED' light signalling  will display if the kh parameter is in safe range. Green color means that the measurement  is in the safe range, red means that the KH parameter is outside the safe range,  the blue color is displayed during the test.

Historical readings

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

Advanced options presented simply

Alerts when KH level  is out of the set range  or when KH parameter  increased or decreased  to quickly

No need for a central computer

All devices operating within the system are equipped with a Wi-Fi module and connect to the system directly.

iOS and Android

The device can be controlled from any place in the world via a phone application or our website.

Wi-Fi connectivity

Without unnecessary cables, the device connects with a home router using the built-in Wi-Fi module.

Smart Reef

The device is ready to be used in Smart Reef - our versatile system designed for comprehensive aquarium management. No expensive central computer is required!

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.

Concentrated reagents 1L and 2,5L Not Included

Reagent Mix Ratio: 1L reagent / 9L RO water. 
Reagent Test Sample: 5 - 15ml (depends on KH level). 

Average reagent of 1L provides 1,429 tests, cost €0.035 cent per test.  

Smart Reef will notify when reagent is low.
