Dissolved Oxygen Portable Meter
Model Orion Star A123 from Thermo Scientific


Description
Thermo Scientific Orion Star A123 Dissolved Oxygen Portable Meters combine simplicity with accuracy.
A large LCD displays dissolved oxygen readings along with temperature.
Icons provide quick updates on battery life and completed calibration status.
Simple button layout and onscreen messages help with calibration and setup menu choices.

Features and Benefits
  • Large, informative screen clearly shows the main information, including DO reading in mg/L or % saturation, temperature in ºC or ºF, meter mode and battery life
  • Automatic temperature, manual salinity input and manual barometric pressure compensation for an accurate result
  • Don’t miss a reading – AUTOREAD ™ locks in the stable reading on your screen and ready indicator alerts when readings are stable
  • Two calibration options to meet your procedural requirements: water-saturated air method or a Winkler titration
  • Accepts Thermo Scientific Orion polarographic dissolved oxygen probes
  • Non-volatile memory holds up to 50 data points
  • Four AA batteries (included) provide over 2000 hours of operation or purchase the universal power adapter (sold separately) to run meter on AC power
  • Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing
  • 3 year meter replacement warranty
