LT – WJB02 Lead core concentrator | lead core concentration tester
Technical parameters
| This machine is an experimental instrument for measuring the concentration of pencil lead. Measurement of the reflected optical density (represented by the symbol d) of the lead on a specified sample paperReflector optical density: d=Lg1/R450, where R450 is the diffuse reflection brightness factor of sample for blue light with a wavelength of 450nm, i.eGiven the direction, the ratio of the sample's reflected brightness to the ideal diffuse brightness under the same conditions. |
