Abbemat digital refractometers allow fast and non-destructive refractive index measurements. They are factory calibrated with official standards from the Physikalisch-Technische Bundesanstalt (PTB, National Metrology Institute of Germany). Refractive index results from Abbemat 300/350 are accurate to ±0.0001 nD; Abbemat 500/550 provides an accuracy of ±0.00002 nD.

All Abbemat 300/500 refractometers provide full compliance with 21 CFR Part 11, with user levels, audit trail, and forgery-proof data export. Anton Paar also provides a qualification documentation package (IQ/OQ/PQ).
