The precise and durable multi-ion sensor, specially developed by GHL for seawater analysis, requires no reagents, cost-effective calibration 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

Unique multi-ion sensor
Compact and precise multi-ion sensor in laboratory-grade quality, specially developed by GHL for seawater analysis, which combines the functions of several sensors.

No reagent liquids required
There is no need for reagent liquids for measuring.

Precise measurement
Extreme accuracy due to special electronics, sensors and measuring algorithms developed and perfected by GHL.

Cost-effective and harmless reference liquid
Economical measurements due to low consumption and inexpensive reference liquids.

Adjustable measurements per day
The number of measurements per day can be set, additional measurements can be started manually at any time.

Automatic calibration
In order to achieve the maximum possible accuracy, a fully automatic calibration of the sensor is carried out before each measurement.

Measured-value history
Utilizing the measurement value history, you can interpret past measurement results and react to fluctuations.

Automatic adjustment of dosing amounts
In order to achieve stable water parameters, ION Director® can automatically readjust dosing quantities of supplied liquids depending on the measurement result.

LED Status Display
The LED-illuminated GHL logo conveniently provides color-coded status indicators. The various colors show you the condition of your system at a glance.

White = Configuration mode
Blue = Normal operation
Green = Measurement or dosing in progress
Yellow = Warning threshold – fluid container(s) are running low
Red = Alarm threshold – fluid container(s) are empty

WiFi, App and much more
GHL devices offer the most connectivity options, you can choose between app, cloud, web interface or PC software via WiFi/LAN or USB.

Seamless integration in the GHL system
Through the use of the PAB (ProfiLux Aquatic Bus) connection, IOND seamlessly integrates into the modular GHL system. The PAB connection ensures interference free communication with other GHL PAB-devices such as the GHL Doser 2.1 or the ProfiLux® 4.

Low maintenance design
The multi-ion sensor is easily accessible thanks to the well-thought-out design of the ION Director® and can be easily cleaned or replaced if necessary.

Measured values always available from anywhere
Find out about measurement results at any time and from anywhere – via app, cloud, web server or Windows software. Display additionally values and states on the ProfiLux 3/4 display or ProfiLux Touch, if present.

Robust device in laboratory quality
The design of the ION Director® meets laboratory requirements. Like all our instruments, it is made of high quality materials to ensure a long service life.

Technical Specifications
ION Director® is available in two color options: Black or white

Dimensions (mm): 220 x 150 x 75 mm (w/out sensor)

Dimensions (in): 8.66″ x 5.9″ x 2.95″ (w/out sensor)

Scope of Delivery
ION Director® includes the following:

Device with integrated measuring cell
Multi-Ion sensor, especially designed for the IOND, incl. calibration liquids
Silicone tube 5m
Power-supply splitter-cable

ION Director pairs perfectly with the KH Director
KH Director
ION Director, White
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.

4 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 this. After automatic calibration, a sample of the aquarium water is pumped into the ION Director®.

After the measurement has been completed, the sample water is pumped out again and 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.

Configuration options
The ION Director® can be operated in two ways:

1.The ION Director® is connected to the GHL Doser 2 (2.1) Standalone via the ProfiLux Aquatic Bus (PAB).

Doser 2 and ION Director
In this configuration, the GHL Doser has control over the measuring process: It controls the dosing pumps and evaluates the measuring results.

2.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).

P4, Doser 2, IOND
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.

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″).
