Low maintenance

Maintenance of the 9240 analyser requires reagent replenishment only every 100 days and annual replacement of reagent tubing and the sodium electrode. Clear step-by-step instructions are provided to simplify maintenance operations.

Automatic electrode reactivation optimises operation and response time

To maintain optimum response time, even in systems of continuous low sodium concentration, the 9240 analyser provides automatic electrode reactivation. Reactivation uses non-hazardous chemicals and eliminates the need for manual reactivation or electrode etching.

Easy to operate and maintain with automatic calibration

Fully automatic calibration of the 9240 analyser avoids risk of contamination or human error. The system follows a multiple calibration step cycle to eliminate user variability and possible sample contamination. A convenient grab sample feature allows the user to check operation or measurement of a one-off process sample to reduce laboratory time. Unlike other analysers, a manual sample (250 mL) can be introduced without disconnecting any tubes. After sampling, the analyser automatically returns to on-line monitoring.

Data and diagnostics

The system displays comprehensive information for each sample stream. A built-in data logger captures measurement readings, calibration results and alarm information for future access. A step-by-step menu and submenu guides the user through all configuration, maintenance, and troubleshooting.
