4001-series Photometric Analyzer

  • Overview

  • Technical Specifications

The 4001-series Photometric Analyzer employs the DPD method to determine the concentration of free chlorine, total chlorine, chlorine dioxide, ozone, peracetic acid, bromine, permanganate. etc.

Photometry provides a quantitative measurement of organic and inorganic compounds based on colorimetric characteristics. Chemical reagents create linear color intensities proportional to the concentration of a substance at a known, visible wavelength in the visible spectrum (400 to 800nm) with few interfering substances.

• Sample taken for wash / rinse / sample
• First sample measure serves as Photometric Zero
• Peristaltic pump introduces reagents
• Sample is stirred to develop the colorimetric reaction
• Measure the absorbance (Optical Density)

The differential measurement is processed and transformed into a concentration value, through the use of specific correlation tables developed in our laboratories. The controller displays the measurement in mg/l to control dosing.

The 4001-series running costs and maintenance are very low and calibration is carried out automatically with each measurement cycle.

Industrial applications include the analysis of drinking water, wastewater, and aqueous streams in the processing of food, pharmaceuticals, chemicals, etc.
