AR70 Automatic Refractometer The Reichert AR70 Automatic Refractometers are among the most technologically advanced instruments available for measuring Refractive Index, Brix, or equivalent concentration units. These instruments incorporate an advanced Peltier thermal regulation system allowing the user to manually set the desired operating temperature on the easy to use graphic display. Within moments, the instrument will stabilize at the set temperature, eliminating the need for an external water bath circulator. Temperature may be set from 10 to 100 Degrees Celsius. Automatic Temperature Equilibration Detection allows the user to load a hot or cold sample and immediately press the read button. Sample temperature is monitored until an equilibrium is reached with the instrument, at which time the reading will be taken. This ensures the highest level of reading accuracy without the need for a technician to monitor temperature or set a delay timer. Advanced optics (including a sapphire prism for a virtually indestructible sample interface, as well as a 3600 cell sensor) provide the incredible accuracy of +/- 0.0001 Refractive Index and +/- 0.1 Brix accuracy. This is achieved across the entire reading range of 1.3300 to 1.6000 Refractive Index and the full Brix range. While these features are ideal for the Research and Development department, these instruments are also well suited for the production line. With an incredibly simple to use, operator friendly software system and graphic LCD display, anyone can accurately and confidently operate an AR70 Automatic Refractometer. Tested extensively throughout the food and beverage, chemical, and pharmaceutical markets. Brand New! Fresh from the Factory! The AR70 is the little brother of the AR700 It incorporates a built-in Peltier temperature control which eliminate the need for a water bath and helps improves accuracy. The AR70 has a range of 1.3300 to 1.6000 Refractive Index and 0 to 95 Brix, with an accuracy of +/- 0.0001 Refractive Index and +/- 0.1 Brix.
