Check the listing for details. Digital Abbe Refractometer Automatic Optical Instrument Color Touch Screen. Condition: New. Listed at 2500.00 USD. Digital Abbe Refractometer Automatic Optical Instrument Color Touch Screen Applications：This instrument can measure the refractive index nD and the mass percentage of sucrose, glucose, F42, F55 HFCS (Brix) of transparent, translucent liquid and solid.The dry solid content of fruit juice, vegetables, soft drinks and canned goods. Visual targeting, color LCD touch screen display, friendly human-machine interface, intuitive and easy to understand, measurement data can be saved and traced.Temperature correction can be made by measuring Brix. Prism made of hard glass, showing excellent corrosion resistance and scratch resistance.Can widely be used in petroleum, chemical, pharmaceutical, sugar refining and food industries, as well as in related colleges, universities and scientific research institutions for measuring the refractive index nD of transparent, subtransparent liquid or solid substance.Principle:The operational principle of the ABBE refractometer for measuring the refractive index of the transparent or subtransparent substance is based on the measurement of the critical angle.The observation system composed of the visual telescope unit and dispersion correction unit can be used to aim at the dividing line between the bright area and the dark area, that is to aim at the critical angle.The angle-digit conversion unit can be used to convert the angular magnitude into digital magnitude, which will be sent into the microprocessor system for being data-processed.Then, the refractive index, Brix, dry solid content of the sample being measured will be displayed digitally.Feature:Measurement of refractive index nD of transparent or translucent liquid and solid substancesMeasurement of the Brix of sugar solutionAutomatic correction of the effect of temperature on the BrixPrism made of hard glassIt works with 589nm wavelength and uses LED as light source.Specification:Measuring range: Refractive index nD : 1.30000-1.72000, Brix (BX) : 0-100%Measuring accuracy (average): Refractive index nD ±0.0002, Brix：±0.1%Measuring resolution: Refractive index nD: 0.00001, Brix：0.01%Temperature(Min. 0.1℃): Temperature display range : -20-120℃Display: Color touch screenInterface: RS232 / USBDate Storage: 500 setsOverall dimensions of the instrument : 330mm×180mm×380mmWeight of the instrument : 10kgPower supply : AC 220V-240V frequency 50HzInput power : 30WUsage temperature range : room temperature — 35℃Fuse : F/A250V 1AProtection grade : IP20
