Field of application
The OUSAF44 UV sensor monitors the concentration of your product in process liquids. Its outstanding filter performance ensures highest linearity and full consistency with lab results. This provides you with fast and reliable process information and increases the yield of your product. You also benefit from EasycalTM – the patented system for easy, liquid-free online calibration traceable to NIST. OUSAF44 is approved for hazardous areas (ATEX, FM) and suitable for hygienic processes (CIP/SIP).
The OUSAF44 sensor measures the UV absorption for:
Measurement of protein concentrations
Chromatography control
Permeate and retentate monitoring
Concentration measurement of organic compounds
Aromatics detection
Filter monitoring
With its international explosion-protection approvals, such as ATEX and FM, the sensor is suitable for hazardous area use.
Benefits
Fast and reliable monitoring of product concentration for better process control and simplified quality control
