IQ fixed cable measuring cell for digital conductivity measurement

IQ fixed cable conductivity measuring cell TetraCon® 700 IQ F

Digital fixed cable measuring cell with 4 electrode system - the TetraCon® 700 IQ F especially for operation as fixed conductivity measuring point with DIQ/S 181(/24 V)

  • Very large measuring rang
  • Quick temperature compensation thanks to integrated temperature sensor
  • Cost-effective alternative for analog measuring point (combined with DIQ/S 181)

The TetraCon® 700 IQ F, together with the monitor DIQ/S 181(/24 V), is an economical solution for your conductivity measurement - regardless, whether in a wastewater treatment plant, in drinking water or in the process. This measuring technique has proven itself over the years and offers an interference-free operation, also and foremost at high conductivity values. With its pressure resistance of up to 10 bar, nothing is keeping you back from mounting this in pipes or lines.
