Automated Alkalinity Monitoring and Control
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.
KH Director uses a modified pH probe to provide KH values. In terms of the KH test process, the 3 blue adapters on the KHD each connect to an available GHL Doser 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.
The GHL KH Director requires 3 pump heads to perform the test, leaving one head open for dosing or any other operation you wish. Many reefers will use Tropic Marin All-For-Reef as an all-in-one additive supplement, where others may choose to replace the 100mL sample water with fresh saltwater after every test, how the open head functions is completely up to you!
Extreme efficiency and cost-effectiveness
GHL understands 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.
