ABB Australia  have announced the first three new products in the ABB Aztec 600 range of online analytical analysers for potable water treatment. Built on ABB Australia's new analytical instrument platform, the ABB Aztec 600 Aluminium, Iron and Manganese colorimetric monitors offer enhanced accuracy with simple operation and maintenance for potable water treatment applications.

The analysers use an LED and detector to measure the passage of light through a sample. A single controlled piston pump provides all the sample and reagent fluid handling for measurement, mixing and disposal. Measurements are taken before and after colour reagents are added to compensate for background colour and turbidity. These measurements are compared against the calibrated values to calculate the sample being measured.

The Aztec 600 Iron, Aluminium and Manganese analysers can measure up to six samples per hour. Key features of the Aztec 600 analyser range include automatic two point calibration. This enables operators to verify analyser performance against standards of a known concentration.

Accuracy is enhanced by various self-cleaning abilities to ensure the optical cell and analyser tubing used for sample measurements remain free of residual particles between each analysis. A patented mechanical cleaning function uses the piston movement to wipe the optical cell with every measurement, particularly when measuring raw waters where optical contamination can be a real issue. The analysers also include various user programmable automatic options for cell rinsing and acid and alkali washing.

To maximise the measuring range, the Aztec 600 analyser features automatic sample dilution. This function allows the instrument to be set to automatically adjust to monitor higher levels of samples by using deionised water to dilute the sample.

The analysers are available in single or multi-stream configurations, enabling operators to use just one device to monitor up to three streams sequentially all with current loop, Ethernet or Profibus outputs.

Aztec 600 analysers are also simple to maintain. The piston and optical sensor use air to mix the sample and reagents, eliminating the cost and maintenance associated with mechanical or electrical stirring systems. The inherent product design and auto-calibrating features mean that maintenance is required annually.

A key benefit of the Aztec 600 analyser is its ease of operation. Front-mounted pushbuttons allow easy device interaction in a familiar Windows environment. Operation and commissioning is straightforward, with menus presenting options for setting and fine-tuning parameters. Added support is provided by an extensive context-sensitive on-line help feature.

Based on ABB Instrumentation's successful common operator interface, the Aztec 600 colorimetric analyser features a full colour graphical display, allowing process trends to be easily viewed and analysed locally. Historical logs provide operators with access to alarm and audit trail data. Process data and historical logs are securely archived to a removable SD card with capacity of up to 4GB.

A built-in Ethernet communications link with onboard web and ftp servers enables remote monitoring, configuration selection, data and log file access to the analyser from a web browser.

ABB Aztec 600 analysers are backed up by a comprehensive local service and support network, offering everything from commissioning through to upgrades throughout the life of the product.
