Description
Thermo Scientific™ Orion™ Versa Star Pro™ pH/ISE/Conductivity/Dissolved Oxygen Multiparameter Benchtop Meter, VSTAR94
Features:
- Provides high accuracy, premium performance and ultimate flexibility for most challenging applications for pH, ion concentration, conductivity, dissolved oxygen and temperature
- Customize four meter channels with interchangeable modules
- Measurements for all four channels can be viewed at once on color display along with stability indicator that signals when readings are stable
- Selectable read modes include Auto-Read to hold stable reading, Continuous to show changing readings, Timed to log data at specific intervals and Single-Shot to hold reading after specific wait time is reached
- Audible alarms automatically sound when set offset value, high/low limit value and calibration time interval are reached
- 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 30 most recent calibrations per parameter with viewable graph for multipoint pH and ISE calibrations
- Ensure measurement integrity by viewing active calibration log while taking readings
- Non-volatile meter memory preserves data and settings, even in event of power loss
- Meter facilitates data transfers to computer via USB or RS232 connections
- Pro™ series has system access feature designed to help ensure data integrity by preventing undesired access to various meter functions including date/time setting, data log and calibration log and can be turned off according to lab needs
- When enabled, System Access feature allows assignment of a system administrator and up to 10 user accounts with customizable access to instrument settings, measurement settings, calibrations and logs - use password protection to secure selected meter functions, while leaving other functions accessible for all users customizable to specific security and data reporting needs
Orion™ Versa Star™ pH/ISE Measurement Module:
- Measure pH, ion concentration, mV, relative mV or ORP with temperature
- Perform up to 6 point pH calibration using automatic buffer recognition of NIST, DIN or user-defined buffer groups
- Perform up to a 6 point ISE calibration with selectable units of ppm, M, mg/L, %, ppb or none
Orion™ Versa Star™ Conductivity Measurement Module:
- Measure conductivity, TDS, salinity or resistivity with temperature
- Perform up to 6 point conductivity calibration
Use linear, non-linear, EP (USP) or off conductivity temperature compensation with 5 °C, 10 °C, 15 °C, 20 °C or 25 °C reference temperatures
Orion™ Versa Star™ RDO/DO Measurement Module:
- Measure dissolved oxygen in percent saturation or mg/L with temperature using Orion RDO optical DO probes or Orion polarographic DO probes
- Calibrate DO using water-saturated air, air-saturated water, custom value (Winkler titration) and zero point options
- Automatically compensate DO readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure
