HD2106 Conductivity-Thermometer

Brand: Delta OHM S.R.L.

HD2106.1 and HD2106.2 are portable instruments with 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, contact or air probes. 

The probe calibration can be performed automatically in one or more than one of the 147 μS/cm , 1413 μS/cm , 12880 μS/cm  or 111800 μS/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 RS232C and USB 2.0 serial ports. 

The storing interval, printing, and baud rate can be configured using the menu. 

Both 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 AutoHOLD function, and the automatic turning off which can also be excluded. 

The instruments have IP66 protection degree.
