KH Director® – Features

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.

User-adjustable test sample volume

In practice, an accuracy of 0.1 ° dKH is not 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.

Measurements per day adjustable

If the KH value does not fluctuate strongly the number of measurements can be reduced.

Higher accuracy and saftey provided by additional valves

Test your Alkalinity with confidence and consistency. Built-in valves ensure exacly the same measurement conditios 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.
