    The objects of analysis:
  • drink, surface, waste water
  • aqueous solution of samples of plant, food, soil matter etc.
    Main consumers:
  • official, research and industrial ecological and analytical laboratories
  • laboratories for students
  • agrochemical laboratories
Details of operating the conductivity meters "Expert-002"
  • digital with two lines (162) with a bright illumination of the indicator field
    Selection of the measurement range:
  • automatic and manual
    Presentation of the results of the measurement:
  • SEC (corrected SEC) - Sm/cm, mSm/cm;
  • TDS g/l, mg/l;
  • specific resistance - Ohm, kOhm, MOhm;
  • temperature - 0C.
    The user's interface
  • the possibility to work without PC+ interface RS232C for connection with PC
  • software included
  • simultaneous indication of the conductivity, (or specific conductivity, or TDS) temperature
  • user-friendly menu
    Temperature correction
  • automatic and manual
  • the range of the automatic temperature correction
  • from 0 to +50 0C
    The calculation of the total dissolved salt contents (TDS)
  • the list of saltsfor calculating TDS in the memory of the instrument (NaCl, KCl, CaCl2, KNO3)
  • the possibility to insert the tables for TDS calculatig for up to 2 new salts, selected by the user
    Temperature for correction of conductivity
  • the standard + the possibility to be adjusted by user

    The type of the conductivity sensor
  • conductivity /temperture combination SEC/T- 4-electrode batch or immersible contact sensor.
  • the composition of the electrodes - the stainless steel or graphite
  • the "plug and play" system: the cell of the constant and the calibration of the temperature sensor are stored in a chip in the plug of the cell. So when you change the cell, the instrument recognizes the calibrations and is ready for use with another cell without re-calibrating.

  • autonomic from built-in lead battery or from external source DC 12V
  • the duration of the work, provided by completely charged battery not less than 50 hours
    The memory chip built-in into the conductivity /temperature sensor
  • energy-independent
  • contains the cell constant and the calibration of the temperature sensor
    Metrological data
  • the standard deviation of the specific conductivity measurement 2% from the upper limit of the current range
  • the standard deviation of the temperature measurement: 0,50
  • 20011060 mm
    The mass
  • 0,95 kg
