color measurement with the sensor AF21

AF21 long pathlength flowcell

Low level color sensor

Flow through optical sensor used with a Model 980 dual beam photometer for measuring low level color absorbance in process liquids

  • Includes built-in liquid free calibration aid for quick, simple on-line traceable calibration
  • Can be configured to measure color absorbance at wavelengths between 390nm and 650nm
  • Pyrex optics deliver accurate and reproducible performance under industrial conditions. Fire polished Quartz or Sapphire optional
  • Incandescent gas-filled lamp provides long dependable life and high energy output
  • Dedicated reference detector channel minimises low level turbidity and particulate related measurement errors
  • 100mm to 250mm pathlength range allows flexibility of measurement ranges
  • Measure color at low levels (i.e. 0-10 APHA/Hazen)
  • Air purge ports available for preventing condensate buildup on optical windows
  • FM and ATEX approved explosion proof lamps for hazardous applications
  • All sensors are pre-tested at the factory and can be supplied with full certification package
