HD2106.2 - Conductivity Meter HD 2106.1-2


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 than one of the
147 uS, 1413 uS, 1288 0uS or 111800 uS/cm conductivity calibration solutions.
The temperature probes are equipped with an automatic recognition module and
factory calibration data are stored inside. The HD2106.2 is a datalogger. It memorizes
up to 36,000 conductivity and temperature samples which can be transferred
from the instrument connected to a PC via the multi-standard RS232C serial port and
USB 2.0. 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 to a PC the acquired measurements or to a portable printer in real time. 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 excluded.

The instruments have IP67 protection degree.
