Thermo Scientific Orion Star
™
and Star Plus Meter User Guide
Chapter I
Introduction
Congratulations! You have selected an industry-leading Thermo Scientific Orion Star
or Star Plus series meter that is designed for electrochemistry measurements in the
field or in the laboratory .
• Orion 2-Star meters provide the single parameter measurement of pH .
• Orion 3-Star and Star Plus meters provide the single parameter measurement
of pH, dissolved oxygen, RDO
®
optical dissolved oxygen or conductivity .
• Orion 4-Star and Star Plus meters provide the dual parameter measurements
of pH/dissolved oxygen, pH/conductivity, pH/ISE (ion selective electrode)
or pH/RDO optical dissolved oxygen .
• Orion 5-Star and Star Plus meters provide the multi-parameter measurements
of pH/ISE/dissolved oxygen/conductivity, pH/dissolved oxygen/conductivity
or pH/RDO optical dissolved oxygen/conductivity .
All meters include a temperature measurement function . All meters
with pH measurement capability include a mV/relative mV/ORP function .
Built to meet the demands of busy, multiple user laboratory or plant environments,
all Orion Star and Star Plus series meters are microprocessor controlled, which
aids in the delivery of accurate and precise measurements . The waterproof portable
meters can even withstand submersion for short periods of time .
The 3-Star Plus, 4-Star Plus and 5-Star Plus meters have been enhanced to include
an increased number of datalog points, improved temperature displays and a new
temperature calibration mode for each measurement parameter . Benchtop 3-Star
Plus, 4-Star Plus and 5-Star Plus meters include autosampler capability and are
compatible with the AutoTration
™
-500 autosampler . Refer to the AutoTration-500
user guide for information on operating the Star Plus meters with the autosampler .
Note:
Please read this user guide thoroughly before using your benchtop or
portable meter. Any use outside of these instructions may invalidate your warranty
