Description

The 3S 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 analyzer glass cell. The sample, comining from an external reservoir or process stream is autonomously grabbed by the instrument and mixed with the appropriate reagents to make the reaction happen. The analyzer 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 (analite).

Features:

  • Low reagents consumption and analytical reliability thanks to our custom designed miniature peristaltic pumps
  • Dual compartment design to guarantee a complete separation between the electronics and the hydraulic section
  • Color touchscreen to show the last measured value clearly, and to set all the options and settings via an user friendly interface
  • Datalogger function with data history in graphical form and USB download
  • Automatic calibration, validation and cleaning to reduce down time and operator intervention, their frequency can be freely set by the user
  • Fully integrable in industrial automation via the analog outputs (2 x 4-20 mA channels), digital output (2 relays + ModbusRTU) and digital input (voltage free contact)

The determination ranges of the zinc analyzer vary from trace μg/L to 125 mg/L Zn2+ using the (optional) internal dilution module.

Method

Zinc reacts with the reagent zincon in a buffered alkaline solution to form a blue complex. The absorbance intensity is proportional to the zinc concentration in the sample and is measured at 660 nm.
