Take simple, routine conductivity, total dissolved solids (TDS) and temperature measurements with the Thermo Scientific Orion Star A112 Conductivity Benchtop Meter

An easy-to-use and budget-friendly instrument for basic conductivity analysis in the lab. Obtain temperature compensated readings using linear option with 20 or 25 °C reference temperatures. 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.

The A112 Conductivity Benchtop Meter features a selectable cell constant as well as selectable reading reference temperatures of 20 or 25°C ensure accurate results

  • Large, informative LCD screen clearly shows the main information, including conductivity or TDS reading, temperature, meter mode and power source
  • Thermo Scientific™ AUTO-READ™ ensures you don't miss a reading; it locks in the stable reading on your screen and a ready indicator alerts when readings are stable
  • Included electrode arm and newly designed holder make it easier to maintain and place probes into samples
  • Meter plugs 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
  • Nonvolatile memory holds up to 50 data points
  • IP54-rated housing withstands splashes
  • Meter mounts to wall, saving bench space
  • Warranty: Three-year meter replacement
