Automated Alkalinity Monitoring and Control
Lab-grade KH measurment accuracy
Measure your alkalinity with lab-grade accuracy. With only a 100 ml water sample, the GHL KH Director can provide measurment values with a 0,1 dKH accuracy
- User-adjustable test sample volume
In practice, an accuracy of 0,1 dKH isn't always necessary. For that the test sample volume can be reduced. An accuracy of approx. 0,2 dKH can still be achieved with a smaller water sample - Measurments per day adjustable
If the KH value does not fluctuate strongly the number of measurments can be reduced - Higher accuracy and safety provided by additional valves
Test your alkalinity with consistency. Built-in valves ensure exactly the same measurment 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 measurment - 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. - Kalk reactor control
Alternatively, the KH value can also be influenced by controlling a kalk reactor. - LED-Status Display
The on-board GHL LED logo 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 - myGHL cloud access
Access the KH Director through the myGHL cloud service via GHL Doser 2, 2.1 or ProfiLux 3, 3.1, 4 - Seamless integration
Through the use of the ProfiLux Aquatic Bus connection, KH Director seamlessly integrates into the modular GHL aquarium system.
The PAB connection ensures interference free communication with other GHL devices such as GHL Doser 2.1 and 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
KH Director includes the following:
- Device integrated measuring cell
- pH electrode, especially designed for the KHD, incl. calibrations liquids
- Testing reagent 500 ml
- silicone hose
- Power-supply splitter cable
