HD2306 Conductivity Meter

Model  Description 
HD2306  HD2306.0 Conductivity Meter Thermometer

The HD2306.0 is a portable instrument with a large LCD display.
It measures 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 than one
of the 147μS, 1413μS, 12880μS or 111800μS/cm conductivity calibration solutions.
The temperature probe is fitted with an automatic detection module, with the factory calibration settings
already being memorized inside. The Max, Min and Avg function calculates the maximum, minimum or
average values. Other functions include: the relative measurement REL, the Auto-HOLD function, and the
automatic turning off which can also be disabled. The instrument has IP67 protection degree.
