Laxco™ Benchtop Digital Clinical Refractometer

Laxco™ Benchtop Digital Clinical Refractometers brings measuring of Urine and Blood Plasma SP Gravity and serum protein to a high degree of accuracy, with the ability through its GIBO software to track, measure, graph, & export data.

Manufacturer:  Laxco™ RHDB501

Catalog No. RHDB501

Includes: Digital refractometer, Prism cover, Calibration fluid, Hard shell case, battery, Applicator, GIBO software, Manual



Laxco™ Digital Benchtop incorporates a linear CMOS sensor for high precision readings that are repeatable.  The sapphire measuring surface is harder than standard glass, and protect against scratches, which can cause inaccurate readings over time. It’s 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.
