Introduction to the AR-200 digital refractometer

The AR200 digital handheld refractometer gives you lab accuracy with a handheld unit: twice the accuracy, twice the range, at half the cost of other units. And it’s easy to use. The state-of-the-art AR200 digital handheld measures refractive index, % solids as Brix, or concentration over a broad range: 1.3300-1.5600 nD (0 to 95% Brix) with exacting accuracy to ±0.0001 nD (+/- 0.1% Brix).

The AR200 is engineered with a new sapphire prism that delivers 2.5x more conductivity to temperature than a conventional glass prism, providing greater accuracy of the Automatic Temperature Compensation (ATC) calculation. The result? A more precise measurement every time!  4x harder than glass, the sapphire prism is resistant to demanding applications, providing lasting durability and service over the life of the refractometer.  

Optional IR Communications Package enables reading log, calibration log, and custom scale transfer to any lab PC.
