Refractometers measure the degree at which light bends as it passes through a medium, and is used in a wide range of applications and industries as a quality control & diagnostic tool.  Laxco™ Digital Benchtop incorporates a linear CMOS sensor for high precision readings that are repeatable. The sapphire measuring surface is harder than standard glass, protecting it against scratches, which can cause in accurate readings over time.

The small, light weight footprint makes it both portable and sturdy enough for benchtop use, while its 5-inch LCD displays offers convenient reading.  Each unit is inspected in the United States by a factory qualified technician under a ridged quality control process to insure its accuracy, and performance.
