New Addition to the Orion Star Series Offers Accuracy and Precision in a Handheld Unit

Beverly, Mass. – July 28, 2006 Thermo Electron Corporation, a world leader in electrochemistry technology, today announced the Orion 5-Star pH meter, the newest addition to Orion Star™ Series, a line of meters, electrodes, accessories and solutions for electrochemistry measurement. The portable Orion 5-Star meter is capable of measuring pH, mV, salinity, TDS, ORP, dissolved oxygen and conductivity, and can be purchased by itself or in a convenient package including all electrodes, buffers and a field case.

Designed to respond to customers' needs for simultaneous measurement and display of pH, conductivity, DO and temperature measurements, the Orion 5-Star meter is designed to meet the IP67 waterproof rating, ensuring that it stands up to the most demanding field measurement conditions. In addition, the unique Smart Averaging™ feature in the Orion 5-Star provides faster meter response time and increased accuracy and precision without user intervention.

'A major university in Germany is already using our Orion 5-Star meter kit to test the water quality in mountain streams and determine the environmental effects of pollutants such as acid rain,' said Anand Shirur, v ice president and general manager of Water Analysis Instruments at Thermo Electron . 'They are most excited about the convenience of Orion 5-Star, especially the ability to test multiple elements in an easy-to-use, transportable field case. For the university and all our customers, the Orion 5-Star will bring lab-quality measurement to the field.'

Significant features of the Orion 5-Star pH meter include:

  • Waterproof minDIN locking electrode connectors to ensure a secure connection;
  • Smart integration between the conductivity and DO channels such that the meter uses the salinity measurement from the conductivity probe for a more accurate DO measurement
  • Auto buffer recognition to improve ease of use;
  • 200 point datalogging including time and date stamp;
  • Custom backlit display for visibility in low light environments;
  • Star Navigator 21 TM Software to enable compliance with the FDA 21 CFR Part 11 regulation.
