Heathrow Scientific 43004 Brix/Specific Gravity Refractometer, Industrial Grade This Brix/Specific Gravity Refractometer features large scales that are easy to read with clear, sharp figures, screen shading, and incredible contrast. This refractometer also comes with a rubber grip on the body, which blocks the transmission of hand heat to eliminate temperature errors. Additionally, the optical glass prism is mounted in an all-metal housing, allowing the sample and prism to reach temperature equilibrium more quickly. This unit also includes a non-roll stand to help ensure stability when placed on a table or benchtop. Each unit comes with a 5-year warranty and includes a zippered vinyl carrying case, plastic transfer pipette, and instruction manual.
