UV absorption sensor
OUSAF46

OUSAF46 UV absorption sensor with two wavelengths ©Endress+Hauser

Sensor for inline product quantification at two specific UV wavelengths

The OUSAF46 UV sensor monitors the concentration of your product at two discrete wavelengths. It covers a broad concentration range and supports you e.g. in optimizing chromatography control. Its outstanding filter performance ensures highest linearity and full consistency with lab results. This provides you with fast and reliable process information and increases your product yield. You also benefit from Easycal – the patented system for easy, liquid-free online calibration traceable to NIST.
