The HD2106.1 and HD2106.2 are portable instruments with a large LCD display. They measure conductivity, liquid resistivity, total dissolved solids (TDS) and salinity using combined 4-ring and 2-ring conductivity/temperature probes. Temperature
only 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/cm, 1413μS/cm, 12880μS/cm or 111,800μS/cm conductivity calibration solutions.
The temperature probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside.
