Product Description
Automated Alkalinity Monitoring and Control
The upkeep of Alkalinity is the most important aspect of reef keeping, stability is key. If you’re looking to achieve exceptional coral growing conditions, Alkalinity testing is a must!
Keep it steady with the new KH Director. Monitor, maintain and control Alkalinity with ease.
Measure your Alkalinity with lab-grade accuracy. With only a 100 ml water sample, KH Director® can provide measurement values with 0.1° dKH accuracy.
User-adjustable test sample volume - In practice, an accuracy of 0.1° dKH is not always necessary. KH Director offers the option to reduce the test sample volume for each test. An accuracy of approx. 0.2° dKH can still be achieved with a smaller water sample.
Measurements per day adjustable
If the KH value does not fluctuate strongly the number of measurements can be reduced.
Higher accuracy and safety provided by additional valves
Test your Alkalinity with confidence and consistency. Built-in valves ensure exactly the same measurement conditions and prevent the sample liquid from flowing back into the aquarium, even in the unlikely event of a fault.
Cost-effective and safe reagent fluid
Each test requires only 1 – 3 ml per measurement.
Automated Data-logging
Examine past test results, catch sudden KH swings, and fine-tune your KH dosing with help from automated data logging.
Automated liquid supply
Automatic supply of KH-boosting liquids. Depending on the method one or more additional dosing pumps required.
Calcium Reactor Control - Alternatively, the KH value can also be influenced by controlling a calcium reactor.
LED Status Display - The on-board GHL LED logo conveniently provides color-coded status indicators. The various colors show you the condition of your system at a glance.

- White = Configuration mode
- Blue = Normal operation
- Green = Amount of liquid in a fluid container is OK
- Yellow = Warning threshold – fluid container(s) are running low
- Red = Alarm threshold – fluid container(s) are empty
Through the use of the PAB (ProfiLux Aquatic Bus) connection, KH Director® seamlessly integrates into the modular GHL aquarium system. The PAB connection ensures interference free communication with other GHL PAB-devices such as the GHL Doser 2.1 or the ProfiLux 4.
Low maintenance design
The KH Director’s unique design makes it easy to access and maintain the included pH electrode. Calibration and replacement, made easy.
KH value display
View your KH reading whenever, where ever you want via the ProfiLux display, ProfiLux Touch or web browser (myGHL), additional external display unit optional.
Robust design built in laboratory quality
Every product we build is made to last the test of time. The KH Director is no exception. Down to the finest of details, the KH Director is build of durable material and is corresponding laboratory requirements.
How it works
The KH Director is designed to work in conjunction with a GHL Doser 2 (2.1) Standalone or a ProfiLux Aquarium Controller 3 or 4 with a Doser 2 (2.1) Slave for operation.The 2 inlets and 1 outlet of the KH Director connect to 3 dosing pumps on the Doser 2 (2.1). These 3 pumps are then responsible for accurately transferring fluid to and from the KH Director.A sample of the aquarium water is first sent to the KH Director. Subsequently, the KH value is determined precisely with slow addition of a further liquid (reagent) and measurement of the pH value.The sample water is then pumped out again and collected in a separate container for later disposal.
A single 1000ml bottle of reagent can last for up to 3 months when testing is performed 4x per day at a KH value of 8. The pH electrode used by the KH Director was specially designed for KH measurement and has an average lifespan of 1 – 2 years.
Configuration options
The KH Director can be operated in two ways:
1) The KH Director is connected to the GHL Doser 2 (2.1) Standalone via the ProfiLux Aquatic Bus (PAB).
With this option, the GHL Doser has full control over the measurement process and behavior of the KH Director. The GHL Doser will control both its dosing pumps and the valves in the KH Director. This will allow the doser to evaluate the measurement results and calculate the KH value.
2) The KH Director is connected to the ProfiLux 3 (3.1, 4) and a GHL Doser 2 (2.1) Slave via the ProfiLux Aquatic Bus (PAB).
With this option, the GHL Doser has full control over the measurement process and behavior of the KH Director. The GHL Doser will control both its dosing pumps and the valves in the KH Director. This will allow the doser to evaluate the measurement results and calculate the KH value.
