IOND and GHL Doser 2.1 SA Set

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).

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.

Features and Benefits:

Unique multi-ion sensor – 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.

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

Precise measurements – 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 – 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 – TThe 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 = Amount of liquid in a fluid container is OK
  • 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 with GHL Systems – 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 designbuilt 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.
