Specification

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 147¼S, 1413¼S, 12880¼S or 111800¼S/cm conductivity calibration solutions. The temperature probe is fi tted with an automatic detection module, with the fac-tory 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.
