Phosphate Colorimetric
Online Analyser

The Phosphate 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:

  • Power Utility
  • Cooling water
  • Drinking water
  • Boiler feedwater
  • Industrial and municipal wastewater
  • Surface water


Application

Phosphates are present in a number of products that are used
by human everyday.

Phosphates are also extensively used in detergents and cleaning fluids because of their ability to soften water and remove soil deposits.

The largest use of phosphates is in the conversion of the mineral content, which is a mixture of calcium phosphate and other calcium compounds that are used in fertilizers. However, high concentrations of phosphates in agricultural runoff can cause environmental pollution, as they are primary cause of eutrophication.

For these reasons, it is necessary to closely monitor the phosphate levels present in both municipal and industrial wastewater.

This Phosphate Colorimeter will measure the phosphate
content in water 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
