Introduction
Congratulations! You have selected one of seven models of the industry-leading
Orion Star Series meter designed for electrochemistry measurement in the field or
in the laboratory.
• 2 & 3-Star meters provide single measurement of pH, Dissolved Oxygen,
or Conductivity.
• 4-Star meters provide dual-parameter measurement of pH/DO, pH/Conductivity,
or pH/ISE (ion selective electrode).
• The 5-Star meter provides multi-parameter measurement including mV/ORP.
Built to meet the demands of busy, multi-user laboratories or plant environments, all
meters are microprocessor controlled aiding in the delivery of accurate and precise
measurements. The waterproof portable meters can even withstand submersion
for short periods of time without any negative effect on operation. To better meet
the needs of users in environmental protection and control, food and beverage,
pharmaceutical, and consumer product laboratories, the Orion Star Series include
these key features:
•
Password Protected Methods – Meter’s memory will save up to ten custom
measurements and calibrations for future reference. Password protection of
each method eliminates any tampering with methods as multiple users access
only the procedure most appropriate to their work.
•
AUTO-READ™ – The instrument automatically starts a measurement and
automatically prints or logs data when the reading becomes stable.
