Handheld (Analog)

A traditional handheld refractometer is a type of refractometer, measuring refractive index that works on the critical angle principle. They are still used today as an inexpensive alternative to digital laboratory refractometers. It utilizes lenses and prisms to project a shadow line onto a small glass reticle inside the instrument, which is then viewed by the user through a magnifying eyepiece.

These instruments may have calibrated reticules that offer readability in units that include refractive index, Brix and other qualified units of measure that include clinical and chemical technologies.

There have been many refinements regarding ease of use and precision to these instruments over the decades which have culminated in the development of the Master Series which fulfil the requirement of users.
