OUSAF22 is an optical sensor for precise inline color measurement in liquids in the visible region of the electromagnetic spectrum. It measures the slightest color changes, ensuring the highest quality standards of your products. Moreover, it provides you with fast values according to all standard color scales and avoids complicated and expensive sampling. OUSAF22 is ready for all kinds of environments, from hazardous areas (ATEX, FM) to hygienic processes (CIP/SIP).

The OUSAF22 sensor measures color for:

• Quality control / Purity monitoring
• Color dosage
• Decolorization control
• Distillation monitoring

This makes it fit for many industries such as

• Life Sciences
• Chemicals
• Food & Beverages
• Oil & Gas
• Water

Color scale measurements: APHA/Hazen, Pt, EBC, ASBC, ASTM, ICUMSA, Lovibond

With its international explosion-protection approvals, such as ATEX and FM, the sensor is suitable for hazardous area use.
