HD2156 pH and Conductivity Meter
| Model | Description |
|---|---|
| HD2156.1 | HD2156.1 pH meter-Conductivity Thermometer |
| HD2156.2 | HD2156.2 pH meter-Conductivity Thermometer Data logger |
The HD2156.1 and HD2156.2 are portable instruments with a large LCD display.
They measure pH, mV,
redox potential (ORP), 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 pH electrode calibration, as well as manual, can be carried out on one, two or three points and the
calibration sequence can be chosen from a list of 13 buffers.
The probe calibration can be performed automatically in one or more of the 147μS, 1413μS, 12880μS or
111800μS/cm conductivity calibration solutions.
