Automatic alkalinity testing made possible by the KH Director. This set is perfect for those who want to test and control their Alkalinity without needing an entire controller system. Better yet, users can enjoy the convenience of expanding their dosing system by adding additional dosing units (EXT) and ION Director! If you already own a GHL Doser SA or ProfiLux 4 controller, we recommend the KHD EXT Set instead.
Set includes:
- KH Director
- GHL Doser 2.2 Standalone
- KHD pH-electrode
- Calibration fluids
- 500ml Reagent
- PAB cable
- Tubing.
GHL KH Director – Monitor, maintain, and control Alkalinity with ease
The upkeep of Alkalinity is the most important aspect of reef keeping. If you’re looking to achieve exceptional coral growth, Alkalinity testing is a must!
The KH Director is the result of more than 2 years of research and development into the automated Alkalinity monitoring and control department. As always, we’ve stuck to our fundamental belief in high quality and exceptional reliability to bring you a product that is built to last. Featuring a patent pending design, KHD utilizes lab grade quality test standards to provide precise results every time. KHD is built to provide aquarium hobbyists and professionals with a safe and reliable Alkalinity control product which presents great value, functionality, and practicality.
Automated Alkalinity monitoring and control
KH Director uses a modified pH probe to provide KH values. In terms of the KH test process, the adapters on the KHD each connect to an available GHL Doser 2.2 or 2.1 dosing unit. One pump is used to feed tank water into the KHD. The second pump feeds the KHD with reagent fluid. The third pump extracts the test sample and used reagent fluid after a completed test, then dispenses it into a waste bin.
As tests occur, the 3 pumps automatically perform their assigned tasks and report the results onto a viewable data logging chart. This data is then viewable on myGHL, ProfiLux Touch, ProfiLux display, and additional external display unit.
Lab grade KH measurement accuracy
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.
Extreme efficiency and cost-effectiveness
Here at GHL we understand the importance of on-going costs involved with automated KH monitoring and control. For the KH Director it was especially important to consider these costs and develop a highly-efficient, cost-effective product. 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.
KH Director requirements
To operate the KH Director, you will need to have at least 3 available dosing pump motors.
This KHD / Doser Set gives you everything you need to get started with automated KH testing and control.
Furthermore, the KHD gives you the flexibility to run the device in one of two ways.
- KHD can be connected to a Standalone Doser 2.2 or 2.1
- KHD can be connected to a Slave Doser 2.2 or 2.1 and ProfiLux 3 or 4 controller
