Included Measurement Modules
Orion Versa Star pH Measurement Module
The included pH module provides accurate measurement of:
- pH
- mV
- Relative mV
- ORP
- Temperature
It supports up to six-point pH calibration using automatic recognition of NIST, DIN, or user-defined buffers. Additionally, the calibration editing function allows individual calibration points to be adjusted without performing a complete recalibration.
Orion Versa Star Conductivity Measurement Module
The conductivity module measures:
- Conductivity
- Total Dissolved Solids (TDS)
- Salinity
- Resistivity
- Temperature
The module supports up to six-point conductivity calibration with calibration editing for individual calibration points. Furthermore, automatic conductivity ranging delivers consistent readings throughout the measurement range without repeated recalibration.
Users can also choose linear, non-linear, EP (USP), or no temperature compensation while selecting reference temperatures of 5°C, 10°C, 15°C, 20°C, or 25°C.
System Access and Data Security
The Orion Versa Star Pro includes an advanced System Access feature that helps laboratories maintain data integrity and instrument security.
Laboratory managers can enable or disable System Access as operational requirements change. When activated, the system supports one administrator and up to ten user accounts with customizable permissions for measurement settings, instrument configuration, calibration records, and stored data.
Password protection secures selected functions while allowing unrestricted access to others. Consequently, laboratories can meet internal quality procedures and regulatory requirements without sacrificing operational flexibility.
