AR200™ Handheld Digital Refractometer

Use in the lab or in the field for transparent or translucent liquids or semisolids.

• Automatically measures refractive index from 1.3300 to 1.5600 to an accuracy of ±0.0001, and % solids (Brix) from 0 to 95% to an accuracy of ±0.1; better than most benchtop refractometers Results are displayed instantly on direct-reading LCD and can be stored in 225 data-point memory (retrievable using optional IR Link-Up software [13-975-130])
• Calibrate with distilled water setpoint or use up to four customizable calibration points for full compliance with NIST™ standards

• Features a special coated glass prism hardened to resist scratching from even the highest solids content samples
• 3600-cell, linear-scanned–array imaging achieves accuracy to ±0.0001n_D, 0.1% Brix
• Temperature sensors and automatic temperature compensation (15° to 40°C [59° to 104°F] per ICUMSA, user-definable in custom scales) enhance reading accuracy
• Auto off/sleep mode extends battery life; low-battery detection built in

• Prism is surrounded by a stainless-steel well; optics and sensing elements are mounted on a fully sealed, ruggedly constructed, diecast frame
• Molded, completely sealed Valox™ thermoplastic-resin housing provides environmental protection and chemical resistance; drop tested from 36 in. (91.4cm)

• Includes single-point or multipoint calibration, four reading modes (RI, temperature-compensated RI, Brix, Brix-TC), and adjustable contrast control
• IR port allows two-way communications with a personal computer if used with optional IR communications package (13-975-130) for stored data retrieval and programming of up to three user-defined channels
