Heathrow Scientific Handheld Refractive Index Refractometer

Our 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.
