The OUSBT66 NIR absorption sensor monitors cell growth, biomass processes, algae systems and crystallization processes. It provides you with reliable, precise measured values in real-time to optimize your process and your product yield. The sensor's hygienic design is CIP/SIP resistant and allows autoclavation. Equipped with NIST-traceable and certified clip-on filters, OUSBT66 is outstandingly easy to calibrate and verify.


  • Real-time measurement for optimized processes and product yields

  • Reliable, precise measured values with excellent laboratory correlation

  • Easy verification and calibration with NIST-traceable clip-on filters - no need for complex liquid calibrations

  • Hygienic stainless steel body and sapphire windows without seals or crevices

  • Suitable for CIP/SIP and autoclaving

  • Various path lengths and sensor lengths for perfect fit into every fermenter and bioreactor

  • PG 13.5 thread for standard assemblies or head plate installations

적용 분야
