B+S RFM990-AUS32 refractometer

RFM990-AUS32 is a highly accurate refractometer designed to meet the strict requirements of the chemical manufacturing industry. It is worth noting that this refractometer complies with ISO standards for producing urea based nitrogen oxide reducing agents (also known as DEF, AUS32, and AdBlue) for use as diesel exhaust fluids ®） Strict procedures.

ISO 22241 stipulates that high-level measurements must be achieved under strict temperature control constraints. In addition to complying with this specification, RFM990-AUS32 is also equipped with specific urea scaling and temperature compensation, as well as AUS32 measurement method, which allows input of the F-factor and biuret content of the solution included in the analysis.

As part of the RFM900 series refractometer, users of the RFM990-AUS32 can also enjoy some common features such as RFID user identification/clearing, local data storage, limit checking, and inspection tracking.

No matter how excellent the instrument performance is, without proper validation, it cannot be confirmed that the instrument meets the performance specifications specified in ISO 22241. Bellingham+Stanley provided a UKAS certified reference material for this purpose, which has a value equal to the urea RI value in the standard.
