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 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.

- 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

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.

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.

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).

 

 

 

 

 

 

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).

 

 

 

 

 

 

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.
