portable measuring device for conductivity and temperature | HD 2106

conductivity, resistivity, TDS, salinity, temperature

general information:

The models 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, contact or air probes. The calibration of the conductivity probe can be performed automatically in one or more of the 147 μS/cm, 1,413 μS/cm, 12,880 μS/cm or 111,800 μS/cm 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 stores up to 36,000 conductivity and temperature samples which can be transferred to a PC from the instrument connected via the RS232C or USB 2.0 serial ports. The storing interval, printing, and baud rate can be configured via the menu. Both 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. 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 IP66 protection degree.

Probes, calibration solutions and cables are NOT included in the scope of supply. Please order separately!
