Iron Colorimetric
Online Analyser

The Iron Colorimeter is a compact analytical instrumentation for online analysis and process monitoring. The colorimeter is based on a color-developing chemical reaction carried out inside the analyser glass cell. The sample from the process stream is autonomously grabbed by the instrument and mixed with the appropriate reagents to make the reaction happen. The analyser uses an LED light source and a photodiode to photometrically measure the developed color intensity (absorbance). The absorbance is proportional to the concentration of the target chemical species (analyte).

The Colorimetric Analyser is the ideal instrument for industrial application such as:

  • Drinking water
  • Industrial wastewater
  • Iron removal processes
  • Boiler feedwater
  • Corrosion control
  • Cooling water
  • Surface water


Application

Iron is naturally present in water in low concentrations, but it reaches high concentrations in wastewater effluents. The iron concentration in water needs to be monitored because it becomes harmful above certain levels.

In domestic water, iron can be unpleasantly alter the taste, stain laundry, damage kitchenware and favour the growth of certain bacteria. Iron is also an indicator of ongoing corrosion in water cooling and heating systems. And it is normally monitored in mining wastewater to avoid contamination.

This Iron Colorimeter will measure the iron content in water and wastewater samples.



Advantages of On-line Analysis

  • Dual compartment enclosure to ensure good separation
    between electronics and hydraulics.
  • Better reliable sampling pump that is able to reach a pump
    height of up to 5 meters
  • Built-in temperature heated controlled reacted measuring cell.
  • Quick testing time, average around 7 minutes.
  • Good repeatability by automation measurement
  • Auto cleaning features that can be programmable
  • Interval testing made possible depends on user requirements
  • Test on demand available for ad-hoc measurement
  • Low reagent level alarm warning.
  • Manual datalogging with RS232 download (Standard)
  • Connectivity to PLC or wireless network by means of 4-20mA
    output or RS485 (optional)
  • Monitoring of multiple streams (up to 4) possible by
    multiplexing configuration (built-in feature)
  • Easy maintenance
