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 147
µS/cm, 141 3µS/cm, 12880 µS/cm or 111,800 µS/cm conductivity calibration solutions.
The temperature probes are automatically detected by the instrument upon turning
on.
The HD2106.2 is a datalogger. It memorizes up to 36,000 conductivity and temperature samples that can be transferred from the instrument connected to a PC via the
RS232C serial port or USB 2.0 port. The storing interval, printing, and baud rate can
be configured using the menu.
The HD2106.1 and HD2106.2 models are fitted with an RS232C serial port and can
transfer the acquired measurements to a PC or to a portable printer in real time.
Display, printing and logging (model HD2106.2) always include temperature in °C or
°F, and one of the parameters of conductivity measure (χ or Ω or TDS or NaCl).
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 instruments have IP66 protection degree.
