Check the listing for details. Monocular Abbe Refractometer Accuracy ±0.0002 Dissolved Solids Brix 0-95%. Condition: New. Listed at 420.00 USD. Monocular Abbe Refractometer Accuracy ±0.0002 Dissolved Solids Brix 0-95% Note:Batteries not included in shipping！！！ Application Scenarios: Abbe refractometer is able to determine the refractive index n D and average dispersion n F-n C of transparent and semi-transparent liquids or solids (of which transparent liquids are the main ones), and if the instrument is connected with a thermostat, it can determine the refractive index n D within the temperature of O ℃ ~ 70 ℃. Refractive index and average dispersion are important optical constants of a substance, which can be used to understand the optical properties, purity, concentration and dispersion of a substance. This instrument can measure the percentage of sugar concentration in sucrose solution (0-95%, equivalent to the refractive index of 1.333-1.531). Therefore, this instrument is widely used, is the petroleum industry, oil and grease industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry, and geological surveys and other related factories, schools and research units indispensable to one of the common equipment.
