Heathrow Scientific 43035 Handheld Refractometer, SX-2, 0 to 28% NaCl, 1/pk

These Sodium Chloride Refractometers feature large scales that are easy to read with clear, sharp figures, screen shading, and incredible contrast. These refractometers also come 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. These sodium chloride refractometers also include a non-roll stand to help ensure stability when placed on a table or benchtop.
