Waterline Fe10/Fe20 (Iron)

OverviewSpecificationsResources

Process analyzers for the determination of dissolved iron (Fe2+, Fe3+)

The WATERLINE Fe10 and Fe20 process photometers can be used for the monitoring and control of the dissolved iron (Fe2+, Fe3+) concentration in water. Measurement principle is the photometric determination of iron by forming a Pyridyl-Triazine compley (WATERLINE Fe10) or by forming a 1,10-Phenanthrolin complex (WATERLINE Fe20).

Main applications for the photometers are the monitoring of the iron concentration in drinking water, waste water and process water.

The analyzers consist of a control unit with touchscreen and an analysis unit with measuring chamber, valve, dosing pumps and all required tube connections. The control unit includes a microprocessor which controls the automatic measurement incl. sampling, rinsing, reagent dosing and surveillance of the photodetection system.

advantages:
  • Automatic measurement incl. self-test and drift compensation
  • Easy operation via touchscreen
  • Adjustable limit value and alarm value
  • Programmable analog output (0/4-20 mA), optionally with USB port for easy data storage
  • Adjustable break time between two analysis
  • External start/stop of an analysis possible
  • No external calibration required
  • External plug connections (IP65) for alarm relay, limit relay, analysis relay, external start/stop, analog output 0/4-20 mA
  • Multi range power supply (110–230 Volt, 50–60 Hz)
  • Including polycarbonate wall cabinet
