Specification         Name: Monocular Abbe Refractometer    Model: WYA-2WAJ Monocular    Measuring range (nD): 1.3000~1.7000    Measuring range (Brix): 0-95%    Accuracy (nD): ±0.0002 (estimated reading)    Average dispersion indication: +0.0005    Temperature display: Digital thermometer    Observation method: monocular    Net weight: 2.6kg    Size: 200*100*240mm                Package Included:    WYA-2WAJ Abbe Refractometer*1                     Instructions:    Abbe refractometer is an instrument that can measure the refractive index nD     and average dispersion nF-nC of transparent and semi-transparent liquids or     solids (which mainly measure liquids). If the instrument is connected to a thermostat,     the temperature can be measured as 0°~ Refractive index nD within 70°c                Sugar Concentration Measurement Range:    The instrument can measure the percentage of sugar concentration in the sucrose     solution (0~95%, equivalent to 1.333~1.531 refractive index)                Applications:    Widely used in petroleum industry instruments, such as paint industry, daily-use food     industry, chemical industry, sugar industry and geology, and one of the indispensable     equipment for schools and other factories and related scientific research units
