Thermo Scientific Orion Star A112 Conductivity Benchtop Meters combine simplicity with accuracy. A large LCD displays conductivity or TDS 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 conductivity or TDS reading, temperature, meter mode and power source
  • Don't miss a reading—AUTOREAD™ locks in the stable reading on your screen and ready indicator alerts when readings are stable Selectable cell constant
  • Â Selectable reading reference temperatures of 20°C or 25°C for an accurate result
  • Included electrode arm and newly-designed holder make it easier to maintain and place probes into samples
  • Plug the meter into almost any power outlet with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power
  • Non-volatile memory holds up to 50 data points
  • The IP54-rated housing can handle splashes and can be wall-mounted if table space is a problem
  • 3 year meter replacement warranty
