Digital IQ fixed cable sensors for dissolved oxygen

IQ dissolved oxygen fixed cable sensors
IQ dissolved oxygen fixed cable sensor FDO® 700 IQ F
IQ dissolved oxygen fixed cable sensor TriOxmatic® 700 IQ F

Optical or electro-chemical: The IQ fixed cable sensors for dissolved oxygen provide reliable measuring values for your single parameter measuring point

  • Save work, time and money with the calibration-free optical oxygen sensor
  • Safe data transfer based on digital technology
  • For wastewater, drinking water and in the process

FDO® 70X IQ F

The optical oxygen sensors can be used universally and have been optimized for the measurement and regulation of the O2 supply in wastewater treatment plants. The membranes of the calibration-free sensors offer different response times. With their 10 m fixed cables, they can be connected to the monitor DIQ/S 181(/24 V).

TriOxmatic® 700 IQ F

For the TriOxmatic® 700 IQ F, the capture of the dissolved oxygen is based on an electro-chemical measuring procedure. The sensor matching the DIQ/S 181(/24V) automatically monitors the electrolyte consumption (SensReg) and the membrane head (SensLeck).
