1. INTRODUCTION
This high precision instrument line is designed especially for
laboratory accuracy. The digital readout eliminates
uncertainties, while the water resistant design facilitates clean
ups and protects the electronics from moist environments. All
models display sample temperature in addition to their other
parameters. Refractometers operate on the principle that, as
the concentration or density of a solution increases, its
refractive index changes proportionately. The larger the
concentration of dissolved substances in the solution, the
higher the reading.
Features include a wide measurement range, automatic
temperature control (ATC), °C/°F selectable scales, high/low
range limit alerts, auto shut off, and a low battery indicator.
