Quality new style refractometers, not the old style. Steel and glass head and prism. These are the INDUSTRIAL Series which feature rugged, drop-tested daylight plates, magnified scales for precise readings, and all-metal construction, which make these handheld refractometers an exceptional value! These analog refractometers are backed and inspected by Laxco, formerly Westover Scientific and Advanced Microscopy Group (AMG).

NOTE: Analog refractometers can be easily calibrated using tap water. However, they cannot be ordered with calibration certification papers. If you need NIST Traceable Calibration Certification, then you must order a Misco digital refractometer.


The RHB Series provide a direct reading of the Brix scale. The Brix scale was developed for working with sugar related liquids (fruit juices, soft drinks, wine), but is also commonly used for controlling the concentration of various industrial fluids (cutting coolants, glycol solutions, and flux rinsing compounds).

NOTE:  We are discontinuing our analog refractometers.  We have only a few models left.
