DRM Digital Refractomete Portable Brix Refractometer

This series of digital refractometers are developed by completely upgrading from our DRB SERIES with high level microprocessors as well as powerful memorizers, which make them have many strong new functions which the DRB SERIES' can not be machable with. It can be said such one instrument can realize all measurements which must be made by the whole series of previous DRB products, in a sense, possessing one set of such instrument would match posessing whole series of our DRB products, that is why we named this series as the "MULTIPLE". Features: Large measure range(0-95%)(NEW)High precision. Automatic Temperature Compensation ( ATC ). (5° C-40° C)Close ATC function. (NEW)Tolerance limit alarm function. (NEW)Stainless steel sample plateAll series of zero calibration function with distilled water. (NEW)Operation humidity: Lower than 90%. Operation sea level: Lower than 2000m. Operation temperature: 0 ° C ( 32° F ) - 40 ° C ( 104 ° F ). Storage temperature: -10 ° C( 14° F ) - 50° C ( 122° F ). Operating time: More than 5000 times per battery. Power supply: 9V Alkaline BatteryCentigrade & Fahrenheit measurementsAutomatic shut off after 3 minutesInstantaneous readingBattery level displayMeasure any solution's refractive index under different temperatures. (NEW)Can be infused new scales needed through intel net by download from us. (NEW)
