Chlorine Colorimetric
Online Analyser

The Chlorine 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).

Designed in compliance with CE electromagnetic standards and using watertight IP54 enclosure, the Colorimetric Analyser is the ideal instrument for industrial application such as:

• Water treatment plants
• Swimming pool
• Disinfection process
• Food Industry

Application

CL412 has been developed to check chlorine dosing in disinfection processes with high concentrations of chlorine. The measurement range provided is ideal for the food industry, such as poultry, fruit and vegetable washing.

This Colorimeter will measure the free or total chlorine content in water.Cl-.

Advantages of On-line Analysis

  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)
