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