Single Channel NIR Absorption Probe, basic version - Type AS56-N

Horizontal Tabs


The model AS56-N is a high-precision, single channel absorption probe. This stainless steel probe, equipped with an Ingold-style port, is designed for use in vessels or inline applications. The sensor uses light in the near infrared (NIR), from 730 to 970 nm. A precisely defined, constant light beam penetrates the process medium. The attenuation of the light intensity, caused by absorption and/or scattering by dissolved and undissolved substances, is detected by a hermetically-sealed photodiode. The optical filter on the lamp side adapts the wavelength for specific applications and allows color-insensitive concentration measurements in the near infrared range. The probe comes with two different optical path lengths (OPL) for process versatility. The seal-less, sapphire window design eliminates crevices and gaps to assure the highest level of sterility, cleanability and sensor integrity. The probe body demonstrates extreme durability and fulfills the CIP/SIP requirements demanded by ultra-sanitary process environments.

  • Inline real time process monitoring
  • Superior sapphire window with no seals, gaps or crevices
  • Concentration measurement insensitive to colour changes
  • Extremely low maintenance
  • CIP/SIP-compatible
  • All wetted material and surface finishes are certifiable and traceable
