Overview

The A112 Conductivity Benchtop Meter is very easy to use, a handy large screen displays on screen messages which help with calibration and setup menu choices. This particular meter features a selectable cell constant as well as selectable reading reference temperatures of 20 or 25°C to ensure accurate results.

The Large informative screen clearly shows all relevant information including conductivity or TDS reading, temperature, meter mode and power source. Thermo Scientific™ AUTO-READ™ ensures stable readings are locked in, whilst the ready indicator alerts when readings are stable.

There are many other features which make the Thermo Scientific™ Orion Star™ A112 Conductivity Meter the perfect meter for simple measurements and these are:

  • IP54 rated housing which withstands splashes
  • A non-volatile memory capable of holding up to 50 data points
  • A three year replacement warranty
  • Meter supplied with universal power adapter, or can be powered using four AA batteries to run the meter on DC power
  • Included electrode arm and newly designed holder make it easier to maintain and place probes into samples
  • Meter can easily be wall mounted, saving bench space

FAQ's

Total dissolved solids (TDS) is a measure of the combined inorganic and organic substances dissolved in water. It is directly related to the electrical conductivity of water and as such can be used as an indication of change.
TDS is only relevant in freshwater systems as salinity will dramatically increase the conductivity and therefore apparent TDS.
