GM Glossiness Meter

Detailed Product Description

1.  Application

 

This instrument is widely used to test surface glossiness of diversified objects such as papermaking, printing, painting, coatings, etc. The geometry, spectrum and photometric characteristics of instrument accord with the relevant standards.

75° gloss method is mainly applied to coated paper and paper board, but also can be used for uncoated paper and board or low printing glossiness of the printed paper and board.

20° gloss method is mainly applied to cast-coated paper, satin paper, glazed paper and other high gloss paper and paper board, but also for high printing glossiness of the printed paper and board, and the high glossiness of printing ink and paint, etc.

45° gloss method is mainly applied to determine aluminum foil paper, vacuum aluminizing paper and other metal complex paper and board.

60° gloss method is mainly applied to various paper, coating, painting, etc.

2.  Executive Standards

4.  Main features

 

Adopts optical-electro-mechanical integration and microcomputer control technology, the instrument has the functions of test data processing and printout. It can measure the surface glossiness of various objects.

(1)  The instrument has a wide range of incident and reflected measuring angles. (75°, 20°, 60°or 45°)

(2)  Uses polished black gloss as glossiness standard. Refractive index is 1.567, and gets ideal glossy surface of black gloss, the glossiness is 100.

(3)  Uses the technology of range expansion, the instrument can measure glossiness of any surface (from the lowest glossiness zero to ideal mirror).

(4)  Power cut-off memory and the instrument print test reports automatically. The computer memory have zero adjustment, sample number, statistical calculation and digital display, and print measured values, average value and statistical results.
