RFM990-AUS32 Fully automatic, digital refractometer for measuring AdBlue®, DEF, AUS32

The RFM990-AUS32 is an extremely high accuracy refractometer specifically designed to meet the stringent needs of the chemical manufacturing industry. Of particular interest is its compliance with the strictest of ISO procedures in relation to the manufacture of ureabased NOx reduction agents used as Diesel Exhaust Fluids, also known as DEF, AUS32 and AdBlue®.
Being part of the RFM900 series of refractometers, users of the RFM990-AUS32 also benefit from common features such as RFID user identity/clearance, on-board data storage, limit checking and audit trails.
No matter how good the instrument performance, without good verification it is not possible to confirm the instrument meets the specification laid down in ISO 22241. Bellingham + Stanley offer a UKAS Certified Reference Material for this purpose at the equivalent RI value of Urea stated in the norm.
