The AVAIN LABS® MA-871 Digital Refractometer is designed for high-precision, rapid measurement of sugar concentrations across a broad spectrum of liquid samples. With a wide measurement range of 0 to 85% Brix, this portable digital meter delivers accurate, reliable results in just 1.5 seconds.
Whether testing food, beverages, agricultural produce, or industrial solutions, the MA-871 ensures lab-grade accuracy with built-in Automatic Temperature Compensation (ATC) to eliminate manual adjustments.
Wide Brix Range: Measures concentrations from 0 to 85% Brix, suitable for fruit juices, soft drinks, jam, honey, and industrial fluids.
Rapid Measurement: Delivers accurate readings in just 1.5 seconds.
Automatic Temperature Compensation (ATC): Operates seamlessly between 10 to 40°C (50 to 104°F) to ensure consistent results regardless of environmental changes.
High Precision LED Optics: Powered by a stable Yellow LED light source for consistent optical readings.
Low Sample Volume: Requires a minimal sample size of only 100 µL.
Dual Display Capability: Reads both sugar concentration (% Brix) and temperature (°C/°F) simultaneously.
