Description

Take simple, accurate dissolved oxygen and temperature measurements with this benchtop meter with easy operation for basic lab testing.

Take simple, routine dissolved oxygen and temperature measurements with the Thermo Scientific™ Orion Star™ A113 Dissolved Oxygen Benchtop Meter. This instrument is easy-to-use and budget-friendly, designed for basic dissolved oxygen analysis in the lab. Calibrate polarographic DO probes using water-saturated air or custom value using Winkler titration. Quickly navigate setup menus and ensure consistent calibrations using the simple keypad layout and on-screen text prompts. Use the included electrode stand to easily place sensors in samples and simplify storage.

Features and Benefits

  • Automatic temperature, manual salinity input and manual barometric pressure compensation for an accurate result
  • Two calibration options to meet your requirements: water-saturated air method or a Winkler titration
  • Non-volatile memory holds up to 50 data points
  • IP54-rated housing handles splashes and can be wall-mounted if table space is unavailable
  • Accepts Thermo Scientific™ Orion™ polarographic dissolved oxygen probes
  • 3-year meter replacement warranty

Multiple Power Options

  • Universal power adapter that works with almost every AC power source
  • Alternative power source of four AA batteries (sold separately)

Easy-to-Read Backlit Display

  • Large, informative screen clearly shows the main information, including DO reading in mg/L or % saturation, temperature, meter mode and power source
  • Thermo Scientific™ AUTO-READ™ locks in the stable reading on your screen and ready indicator alerts when readings are stable, so you don't miss a reading
  • Simple button layout and onscreen messages help with calibration and setup menu choices
  • Icons provide quick updates on battery life and completed calibration status
