Product information "N-LF2000, conductivity measuring instrument 0-20/200/2000μS/cm in wall mounted housing"
Instrument for measuring the electrical conductivity of aqueous solutions in conjunction with two-electrode measuring cells. Designed as wall-mounted version.
  • Operation at 230 V AC or 24 V DC possible
  • 2 potential-free relays - changeover switch for limit value switching (hysteresis 5 % fixed)
  • Alphanumeric display with 2 x 16 characters
  • Temperature measurement and temperature display from 0.0 °C to 90.0 °C when a Pt100 is connected
  • Switchable temperature compensation with 2.2 % / K up to 90 °C
  • Monitoring of the temperature sensor for sensor break and error message on the display
  • Switchable mode of operation for relay control
  • Output of the measured value with 0 - 10 V and 4 - 20 mA

Technical data
