RFM990-AUS32 Refractometer
Featuring a new touchscreen display and wide measuring range up to 1.70 RI and capable of measuring to six decimal places, the RFM900-T Series refractometers are ideally suited for use in the chemical, petrochemical, pharmaceutical, flavours and fragrance industries as well as for academic research.
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 urea-based NOx reduction agents used as Diesel Exhaust Fluids, also known as DEF, AUS32 and AdBlue®.
ISO 22241 dictates the highest level of measurement must be achieved under the tightest limits of temperature control. In addition to the compliance with this norm, the RFM990-AUS32 is fitted with specific Urea scales and temperature compensation as well as an AUS32 Method that allows input of both the F factor and biuret content of the solution that is included in the analysis.
