Advanced Features

Guided Setup and Calibration

The built-in setup wizard walks users through initial configuration and measurement settings. In addition, interactive meter tours explain calibration procedures, electrode installation, meter connections, and routine maintenance.

Guided calibration provides clear step-by-step instructions, helping users perform accurate calibrations and obtain reliable, repeatable results.

Flexible Display Options

The large 7-inch touchscreen offers multiple display layouts, including Basic, Advanced, and Custom measurement views. Consequently, users can choose the amount of information displayed during analysis.

The Graph View simultaneously displays measurement values and temperature over time, making it especially useful for monitoring sample stability and conducting time-based studies.

Sample Handling and Accessories

Users can quickly enter sample identification information using an optional USB barcode scanner, keyboard, or mouse. Meanwhile, the optional meter-controlled stirrer probe mixes samples uniformly without requiring a separate magnetic stir plate.

Data Logging and Record Management

The Orion Pro Star PH211 provides comprehensive data management for laboratories requiring long-term record retention.

The meter stores up to 20 calibration records per parameter with date and time stamps. Moreover, users can filter calibration logs by operator and export selected records or complete calibration histories.

Measurement data management is equally powerful. The instrument stores up to 10,000 measurement records with complete date and time information. Users can search records by user, date, time, or log number before exporting selected data or the entire database.

Connectivity and Data Export

Laboratories can export measurement data, calibration logs, and saved methods directly to a USB flash drive, printer, or computer.

Additionally, the meter saves files in CSV format for Microsoft Excel compatibility or generates printable report files for laboratory documentation. Users can also customize exported reports to include only the information required for their records.

Bidirectional communication further enables integration with LIMS, HyperTerminal, PuTTY, and other laboratory data management software.

Methods and Workflow Standardization

Users can save up to ten measurement methods to standardize routine analyses and laboratory SOPs. Furthermore, methods can be imported or exported between Orion Pro Star meters, ensuring consistent testing procedures across multiple instruments.

Secure User Management

The Secure Mode feature enhances laboratory data protection by supporting up to three administrators and thirty user accounts.

Administrators can define individual permission levels for instrument settings, calibration records, data logs, and measurement functions. As a result, laboratories maintain better control over data integrity while supporting regulatory compliance.

User lists and audit trails can also be exported for additional documentation and quality assurance.

Electrode Stand

The included electrode stand provides smooth and secure electrode movement during measurements. Its weighted base offers flexible positioning around the instrument, while built-in cable management channels keep the workspace organized and uncluttered.
