EziLab offers the Automatic Refractometer EZL-AR171, a laboratory refractometer that reads refractive index from 1.30000 to 1.70000 nD within 0.0001 nD and Brix from 0 to 100%. Resolution is 0.0001, with 0.00001 optional. Peltier control sets the prism from 5°C to 70°C within 0.05°C, while a 7-inch TFT touchscreen, 4 GB storage, and RS232, USB, and Ethernet ports run on 45 W in a 365 by 300 by 150 mm body. A long-life light source and maintenance-free prism keep upkeep low, and cloud service links results to shared records. Operators place a drop on the prism and get refractive index or concentration within seconds, unaffected by room humidity, temperature, or vibration. Automatic warnings flag a dirty prism or too little sample before a bad reading is saved. Built-in temperature control removes the need for an external water bath, so 20°C readings stay comparable. Beverage and sugar producers run routine Brix checks on juices, syrups, and soft drinks, while food plants verify concentrates and sauces. Chemical manufacturers measure acid and salt concentrations, and petroleum labs test oils and fuels for quality control. As a digital refractometer, it suits QC benches. See the Automatic Refractometers and Automatic Refractometer pages for full specifications.
