Fully Automatic Measurement and Control of Ca, Mg, K, Na, NO3
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:
- Control: Automatic readjustment of dosing pumps to keep a value stable
- Monitoring: Alarm when the value is outside an adjustable range
- Analysis: Display in charts and logbook (via app, cloud and web server GHL Connect and GHL Control Center).
Combine the ION Director® with the KH Director® and measure and control the KH value in addition to Ca, Mg, K, Na and NO3.
ION Director® – Features
A compact and precise multi-ion sensor in laboratory-grade quality, specially developed by GHL for seawater analysis, which combines the functions of several sensors.
ION Director pairs perfectly with the KH Director
The ION Director® can be used alone or in combination with the KH Director®.
With the IOND and KHD, you can fully automate the regulation of the aquarium’s key water parameters. While the KHD measures and controls alkalinity, the IOND covers other important parameters necessary to maintain a healthy reef.
Maintaining a healthy reef –
Easily done with the powerpack Ion Director® + KH Director®.
How does the ION Director® work?
The IOND was designed as an accessory device and requires either a GHL Doser 2 Standalone or a ProfiLux aquarium controller (3 or 4) with GHL Doser 2 Slave to operate, see configurations below.
3 pump heads are required to perform the measurement.
To achieve the highest possible measurement accuracy, each test is performed with a freshly calibrated sensor. Two pump heads are used to convey the reference fluids required for the calibration, a sample of the aquarium water is pumped into the ION Director® by the third pump.
Reference fluids and some sample water are collected in a separate container for later disposal.
How can the measured parameters be controlled?
Thanks to the innovative technology of the ION Director®, each parameter can be accurately measured and automatically regulated. If a parameter is too low or too high, the IOND can automatically calculate the amount by which dosages need to be changed to maintain stable values. It is therefore also suitable for different systems such as Balling® (Light) or Triton® .
Choose the optimal control mode for your aquarium and adjust it individually.
After a measurement, the deviation of the real value from the desired value (setpoint) is known. The following control modes operate on the basis of this deviation.
Add-On Control Mode
The set dosing quantities of certain dosing pumps are readjusted depending on the deviation determined, the user sets the quantity (in ml) by which the dosing quantity should change in the event of a certain deviation.
Adaptive control mode
Works similar to the Add-On control mode, but here the user determines the percentage change of the set dosing quantity for a certain deviation.
The ION Director® can be operated in two ways:
The ION Director® is connected to the GHL Doser 2 (2.1) Standalone via the ProfiLux Aquatic Bus (PAB).
In this configuration, the GHL Doser has control over the measuring process: It controls the dosing pumps and evaluates the measuring results.
The ION Director® is connected to the ProfiLux (3 or 4) and a GHL Doser 2 (2.1) Slave via the ProfiLux Aquatic Bus (PAB).
In this configuration the ProfiLux has control over the measuring process: It controls the dosing pumps in the Doser and evaluates the measuring results.
Choose the combination that suits your needs best
Whether you prefer the GHL Doser 2.1 or the P4-Slave Doser combination: thanks to the ingenious design, all devices will fit perfectly with each other no matter if stacked or positioned side-by-side.
We also offer attractive sets for the ION Director® and GHL Doser combinations.
Please note that only one IOND can be controlled by one master device (ProfiLux or GHL Doser Standalone), each IOND requires one dedicated controlling device. In one system (consting of one master device and slave devices) can only one IOND be present.
ION Director® Sets
Operation of the IOND requires always a GHL Doser with 4 pumps, depending on the configuration either as Slave or as Standalone version.
GHL offers these sets:
- IOND + GHL Doser 2.1 Standalone 4-way
- IOND + GHL Doser 2.1 Slave 4-way
Both sets have a significant price advantage compared to buying separately, they are offered in white and black and in these country versions: Schuko, UK, CH, USA/CND, AUS. The sets include a PAB cable (50 cm / 19.6″).
