Abstract
The utility model discloses a sugar color value detection and calibration device, which comprises a bracket, the top of support is seted up flutedly, the through -hole has been seted up to recessed wall's bottom, and the inside of recess is provided with the spring preforming, the spring preforming includes the screw, and the surface of screw is provided with the spring strip, and the equal fixedly connected with crotch in both ends of spring strip is provided with colored glass in the clearance between spring strip and the recess bottom. This sugar color value detection and calibration device, colored glass places earlier the inside at the recess, and then compress tightly through the spring strip in the spring preforming, thereby realize the calibration of sugar color value survey, can be quick convenient examine and determine being little yellow custer sugar color value accuracy of measuring at 420nm spectrophotometer, can be to the non -linear timely discovery of spectrophotometer production when measuring the custer sugar color value, can be to the replenishment of measurement standard material and calibration method among the visible light spectrophotometer examination rules JJG178, the motor driver has great applicability, high reliability.
Description
Technical field
This utility model relates to spectrophotometer performance detecting technical field, is specially a kind of sugar colour testing calibration device.
Background technology
Measure white sugar colour method greatly to as follows: weigh white sugar 100g in 200ml beaker, add triethanolamine hydrochloride buffer solution stirring such as to dissolve, through 0.45 μm filtering with microporous membrane, then contain sugar liquid with cuvette, spectrophotometer measures its absorbance with 420nm wavelength.Calculate the colour of white sugar.
White sugar colour is the key index of White Sugar Quality, and spectrophotometer is the critical equipment equipment measuring white sugar colour, and the quality of its test performance directly influences the accuracy of measurement data, and White Sugar Quality also can be caused to judge by accident.
White sugar colour reference plate by three when 420nm wavelength the special coloured glass of difference absorbance form.When spectrophotometer being carried out white sugar colour and measuring calibration, three white sugar colour sheets are respectively put on spectrophotometric colo frame, spectrophotometer measurement wavelength is adjusted at 420nm, with air as reference, carry out sugar colour measurement, but at present when carrying out sugar colour and measuring, sugar is not calibrated, if not carrying out sugar colour calibration, quickly and easily spectrophotometer cannot be examined and determine in slightly yellow measurement white sugar accuracy of color value at 420nm, spectrophotometer the non-linear of generation when measuring white sugar colour cannot be found timely, metering standard substance and calibration method in visible spectrophotometer vertification regulation JJG178 can't be supplemented, poor for applicability, reliability is low, inconvenient people use.
