Model 2WE ( 2WE-TP 2WE-U Digital ABBE refractoscope

1. Application The instrument is used to determine nD ( the refractive index) and BX( the sugar solution density) and NF-NC( average dispersion) of transparent or semi-transparent liquid or solid. With LCM( liquid crystal modular) to display the test result. it is widely be used to food industry , oil, sugar .petroleum. daily chemistry .geological prospecting . scientific research and teaching department 2. Outstanding ( 1) A circular grating sensor which have zero point as ruler to test critical angle directly and have minimum middle chains, so the instrument have high accuracy and good reproducibility ( 2) The nD and BX can be shown in dynamic in the process of testing to ensure fast and convenient operation. ( 3) Adopt U.S digital-integrative temperature sensor to ensure fast and accuracy to display temperature ( 4) To make BX modifying and dynamic display automatically at starting up. ( 5) The instrument has average dispersion function .when input the ruling value of dispersion wheel the dispersion value of subject can be shown. ( 6) 32 digital LCM except nD and BX or temperature and BX modified display operation instruction timely. ( 7) The instrument design according to human-machine technology operating comfortable 3. Technical parameter ( 1) . Measuring range Refractive index Nd 1.3000-1.7000 Berix BX 0-95 % ( 2) Minimum increment Refractive index nD 0.0001 Berix BX 0.01% temperature 0.1 ( 3) Uncertainty Refractive index nD + / - 0.0002 Berix BX + / -0.05% ( 20 ) ( 4) Reproducibility Refractive index nD + / - 0.0001 ( 5) Range of BX modify 0? 70 ( 6) Dispersion uncertainty + / -0.0005 4.2WE- TP type Besides main function of 2WE-T type it still has printer PP40 interface I/ O.( CENTRONICS) .The demand' s data can be print out. 5.2WE- U type That model not only sugar industry customer but more be applicable in food industry oil, petroleum, daily, chemistry .geological prospecting. scientific research and teaching department Characteristics: ( 1) With the all-powerful, it can the intelligence establish the every kind of table that the function relation ( soft rule) of the thick degree and refractive index automatically, and while testing can be shown. ( 2) The accuracy of soft rule is high, and for an example of BX with the sugar, at 0 ? 95% zone, can reach BX d 0.06% . ( 3) When unknown relation, this instrument after testing several set ( 3 ? 5) subject which the contain is accuracy known, will help you to automatically establish the whole range of function relation
