Libra® Dosing/ Stoichiometry System

Vertex Aquaristik proudly announces the release of Libra Doser/ stoichiometry management device.

After 16 months of extensive R&D and quality/compatibility assessment of many motors and platforms; decision was made to utilize Japanese Wei co• pumps. Superior quality of parts, components and craftsmanship of these motors are unparalleled for industries demanding higher precision and lifetime.

2 different motor types are available for different applications and precision demands:

 • Reliable Japanese DC motor  [email protected] 24VDC /  150 RPM- 1:8 Gear ratio
 • Accurate Stepper-motor  3.2W @24VDC /  0.1125 "/step - 1:8 Gear ratio

 The user can choose at anytime to seamlessly change from one to the other type motor without the need to change the firmware. The motors are connected to the main PCB board via a simple onboard JST® connection. They are automatically recognized by the CPU; choosing the adequate drive program accordingly. Minimum dosing amount of 0.5 ml/dose @ +/- 3% and 75 ml/min dosing capability makes Libra• an obvious choice for the most discerning aquarist.

Further to that 4 layer Touch-panel 3.2" LCD provides an intuitive interface, making the device easy to program and manage. Simple and expert programmings are performed using the on board Touch screen.

The aluminum housing utilized protects the internal components from corrosion and harsh saltwater evironment, while providing the best heat-dissipation index to increase the unit's life time.

Quad-roller pump-heads are accurate and easy to service without the need for any special tools. To open the motor-head simply use a small screw driver to detach the clear motor cover and change the dosing tubes if required. 

Pharmamed tubes provide a high corrosion resistance index to a wide range of chemicals while long-lasting. 

Connection to Cerebra controller and/ or PC for future firmware update is done via USB-B and Slave unit via USB-A; making the device versatile and universal.

Meanwell drivers are supplied for maximum reliability and hassle free operations.

Key-hole hanging brackets are supplied for flush mounting of the device to any surface. Using the break-outs available on the APS/PC side-caps make management of the power or data cords possible in a neat and organized manner.

Another industry-first unique feature to the Lbra doser is stoichiometry management. Using UPC grade chemicals offered by Vertex Aquaristik the user no longer needs to perform complex calculations to measure the amount of chemicals needed to maintain optimal water parameters and/or maintenance of major, trace and/or any other elements present in natural seawater.***

The concept is based on initial input of basic system constants such as:

  • • Net water volume
  • • Desired Parameter saturation
  • • Hysteresis

Onboard CPU will store the input data as a benchmark for all future dosing calculations.

Using the on board Touch-screen the user simply input the parameter's concentration value and with a click of a virtual button, the right amount of the said chemical required for optimal concentration is dosed.

In addition to the dosing system Vertex Aquaristik provides a range of necessary accessories for better management of your dosing requirements; such as libra• Vessel (Aggressive chemical container) and Line-Mag (Magnetic 1/4" tube-holders}. The said accessories are available through authorized Vertex• dealers in different size and configurations for different system's needs and requirements.

Libra dosers are designed and manufactured in-house by Vertex Aquaristik in Austria.

Both DC and stepper motor models will be ready to ship from house of Vertex in Cologne, Germany by or before the end of July 2012.

Love the display and the touch screen. Quality product but I wish it was a little smaller. No more manual dosing.


Been using it for about a year now. There was a little bit of a learning curve in the beginning but it's easy and very accurate to use. Glad I bought this and not one of the cheaper brands.
