CONDUCTIVITY RESISTIVITY METER
HD 3406.2 Conductivity, Resistivity, Total Dissolved Solids, Salinity Meter

HD3406.2 conductivity, liquid resistivity in liquids, total dissolved solids (TDS) and salinity meter.
The HD3406.2 measures conductivity, liquid resistivity in liquids, total dissolved solids (TDS) and salinity
using combined 4-ring and 2-ring conductivity/temperature probes. Temperature is measured by Pt100 or Pt1000 immersion, penetration or contact probes.
The probe calibration can be performed automatically in one or more of the 147μS, 1413μS, 12880μS or 111800μS/cm conductivity calibration solutions.
