Will sell blackmer FB-2

Blackmer FB-2 is designed to measure the coefficient of specular reflection when the geometry of the illumination-observation had/had and reflectance when the geometry of the illumination-observation had/grad directional light flux from surface coatings in the visible region of the spectrum with the goal for quantitative assessment of visual perception by the human eye gloss (GOST 896-69) and white these coatings, respectively. Blackmer is designed for use in all industries where used or manufactured with a coating. Blackmer operated under the following conditions:
1) the ambient temperature from 1 to 40C;
2) atmospheric pressure 84-106,7 kPa (630-800 mm RT.St);
3) relative humidity 80% at the temperature of 25 ° C;
4) supply voltage (220+22);
5) frequency AC power (50+1) Hz;
Index symbols gloss composed as follows: 1) the first two letters "FB" - PV blackmer; 2) the number after the letter designation "2" - the second modification.

• The range of measurements of reflection coefficients when the geometry of the illumination-observation 45 deg/45 deg directional light flux from surface coatings in the visible spectrum, which is a measure of the degree of gloss, 0 - 65%
• The range of measurements of reflectance when the geometry of the illumination-observation 45 deg/0 deg directional light flux from surface coatings in the visible spectrum, which is a measure of the degree of whiteness, 0 - 100%
• The limit of acceptable basic absolute error of the gloss does not exceed + 4%
• The reflectance of the working standard white surface under illumination geometry surveillance 45 deg/0 deg is (93+7)% (exact value is specified in the calibration certificate this working standard white surface, included in the scope of delivery of gloss)
• Mirror reflection coefficient of the working standard shiny surface when the geometry of the illumination-observation had/had is (65+2)% (exact value is specified in the calibration certificate of the work standard shiny surface that is included in the delivery of gloss)
• The price of each division of the scale 1%
