The AR200 is the first digital hand-held refractometer that performs as well as most laboratory-grade automatic Abbe refractometers with the ease-of-use and price of a hand-held. The AR200 has better than twice the range and twice the accuracy at half the price of any other handheld instrument. It even exceeds many competitors benchtop refractometers. It is designed to automatically read your samples with precision comparable to high-end automatic refractometers. Operator interpretation of unclear shadowlines is no longer necessary. It is ideal for a wide variety of industries including food and beverage, cosmetic, pharmaceutical and chemical. It can be used for checking fruit ripeness, solids levels, quality standards, raw material and solvent purity, concentration/mix ratios, and many other applications. It offers direct reading of percent solids (Brix), refractive index (nD), temperature compensated percent solids (Brix-TC), temperature compensated refractive index (nD-TC) and temperature. It may also be programmed to read out in user-defined units such as ppm, specific gravity, freeze point, etc. Computer interface ability, custom scale programming, and automatic temperature compensation make the AR200 the instrument of choice to meet all your testing requirements.
