• Onscreen measurement stability indicator lets you know exactly when your measurements are ready
• Selectable read modes include Auto-Read to hold a stable reading, Continuous to show changing readings, Timed to log data at specific intervals and Single-Shot to hold a reading after a specific wait time is reached
• Audible alarms automatically notify you when a set offset value, high/low limit value and calibration time interval are reached
• Easily access, update and switch your preferred measurement settings, using 10 password-protected methods per channel
• Uniformly mix solutions using up to two meter-controlled stirrer probes that are easy to position and can be quickly rinsed between samples
• Data log collects and date/time stamps up to 2000 measurement sets with optional electrode ID, sample ID and account ID
• Calibration log stores 10 most recent calibrations per parameter with viewable graph for multipoint pH and ISE calibrations
• Ensure measurement integrity by viewing the active calibration log while taking readings
• Non-volatile meter memory preserves data and settings, even in the event of power loss
• Meter facilitates data transfers to a computer via USB or RS232 connections
• IP54-rated housing resists dust and splashes and can be wall-mounted if table space is limited
• Meters include CE, TUV 3-in-1 and FCC Class A certifications
• 3-year replacement warranty

• pH, mV, relative mV or ORP with temperature using LogR technology, ATC probe or manual input
• LogR technology uses the glass-bulb of most pH electrodes to measure both pH and temperature at the same location — ideal for small sample volumes and samples that are difficult to clean
• Perform up to a 6 point pH calibration using automatic buffer recognition of NIST, DIN or user-defined buffer groups with choice to manually enter custom buffer values
• Calibration editing option allows individual points to be fixed without a full recalibration
• Customize measurements to show calibration history and pH electrode condition or simplify to show an extra large pH reading

System Access Feature

Orion Versa Star Pro Meters offer a system access feature that is designed to help ensure data integrity by preventing undesired access to various meter functions including date/time setting, data log and calibration log. The System Access feature can be easily turned on or off as the needs of your lab change for ultimate flexibility in operation and ease-of-use. When enabled, the System Access feature allows assignment of a system administrator and up to ten user accounts with customizable access to instrument settings, measurement settings, calibrations and logs. Use the password protection to secure selected meter functions, while leaving other functions accessible for all users. The System Access feature allows you to customize meter access to meet your specific security and data reporting needs.
