The economical AR5 digital refractometer with Peltier temperature control included makes sophisticated measuring technology available to users on a tight budget. High-end accuracy and a good price point give customers an exceptional advantage in the laboratory. The AR5 is precise, measuring refractive index and % Brix with results accurate to 0.0001 RI and 0.05% Brix. The AR5 is the ideal instrument to perform routine measurements with standard scales and has the ability to be configured for custom measurements. The robust design, sapphire prism and reliable operation make it a workhorse for the laboratory, resisting surface damage from demanding applications.
