Heathrow Scientific 43055 Handheld Refractometer, NDX-2, 1.425 to 1.520 nD, 1/pk

Handheld Refractive Index Refractometer features the largest, easiest-to-read scale available with clear, sharp figures, screen shading and incredible contrast. This significantly enhances overall precision, even when several different people use the refractometer. This refractive index refractometer also comes with a rubber grip on the body, which blocks the transmission of hand heat to eliminate temperature errors.
The rugged construction of this handheld refractive index refractometer will provide years of reliable use. The optical glass prism is mounted in an all-metal housing which allows the sample and prism to reach temperature equilibrium quickly. The non-roll stand ensures that once this refractive index refractometer is placed on a table or bench top, it won't be prone to roll off the surface.
