You have the application – we have the measuring cell! With the conductivity measuring cells by WTW, measurements of 0.0001 µS/cm to 2 S/cm are not a problem. The unique 4 electrode measuring cell compensates for possible contamination and polarization effects. All measuring cells can be connected to the LF monitor LF 298 NTC (exception: TetraCon® 700).

TetraCon 700 – Designed as an immersion encoder specifically for use in wastewater treatment plants
Conductivity measuring cell with 4 electrode system, integrated temperature sensor, anti-slip electrodes and breakage-resistance shaft; measuring range 10 µS/cm to 1000 mS/cm.
Only as replacement armature for analog monitors of the Ecoline® or QuadroLine® series. Still available as digital version (IQ Sensor Net System 181).

TetraCon 325 – for universal applications
4 electrode measuring cell with graphite electrodes and integrated temperature sensor, measuring range 1 µS/cm to 2000 mS/cm.

LRD 01 – for the installation into pipelines
Conductivity measuring cell as V4A model. With integrated temperature sensor (up to 130 °C), measuring range 0.001 to 200 µS/cm, pressure-resistant to 14 bar, 1/2 inch NPT screw thread.

LRD 325 – for the installation into pipelines
Conductivity measuring cell with integrated temperature sensor (up to 100 °C). Measuring range 1 µS/cm to 2 S/cm, pressure-resistant to 10 bar, 1/2 inch NPT screw thread.

LR 325/01 – for pure water measurement
Pure water measuring cell with integrated temperature sensor and flow vessel, measuring range 0.001 to 200 µS/cm. Especially suited for the measurement of low conductivity values such as in boiler infeed water.

LR 325/001 – for trace measurement, also in partial and non-waterous media
High resolution trace conductivity measuring cell with integrated temperature sensor and flow vessel, measuring range 0.0001 to 30 µS/cm.
