The ION Director® (IOND for short) uses state-of-the-art ion-selective technology to automatically and accurately measure essential water parameters – calcium, magnesium, potassium, sodium, and nitrate – with maximum comfort and affordable operating costs.

The precise and durable multi-ion sensor, specially developed by GHL for seawater analysis, requires no reagents, cost-effective reference liquids are used for the automatic calibration. Inaccurate, time-consuming, and costly measuring methods, such as test kits, are a thing of the past.

In addition to measurement, the ION Director® System offers many other functions:

Combine the ION Director® with the KH Director® and measure and control the KH value in addition to Ca, Mg, K, Na and NO3.
