The IST AG LFS1107 conductivity sensor offers a typical cell constant of 0.42 cm-1 and a conductivity measuring range from 10 μS/cm to 200 mS/cm within an operating temperature range of -30 °C to +100 °C. It can also withstand temperatures over 130 °C enabling processes like sterilization by autoclaving. It features a new glass coating for improved chemical resistance.

Further advantages of the LFS1107 thin-film conductivity sensor include:

  • Widest conductivity and temperature range
  • Small footprint
  • Improved chemical resistance1)
  • Excellent long-term stability
  • Integrated RTD for temperature compensation
  • Four-electrode measurement2)
  • Customer-specific sensor available upon request

The IST AG LFS1107 conductivity sensor is available with either Pt/Ni-wires or Cu/Ag-wires with PTFE-insulation (AWG 30) as standard wires.

Conductivity sensors play an important role in determining water quality and are able to measure the conductivity of most electrolyte solutions. IST AG conductivity sensors are an ideal choice for water quality and waste water treatment applications, amongst others.
