The GM glossiness tester produced by Hangzhou Qingtong Boko is suitable for coated paper and cardboard, as well as uncoated paper and cardboard or low printing glossiness paper and cardboard samples. Widely used in industries such as papermaking, printing, painting, and coatings.
Detailed introduction of GM glossiness tester
1、 Product Introduction
GMGlossiness testerWidely used in industries such as papermaking, printing, painting, and coatings to measure the glossiness of object surfaces. The geometric, spectral, and photometric characteristics of the instrument comply with relevant standards.
75° GlossinessMeasurement methodMainly suitable for coated paper and cardboard, it can also be used for printing samples on uncoated paper and cardboard or paper and cardboard with low printing glossiness;
20The glossiness measurement method is mainly suitable for high glossiness paper and paperboard such as cast coated paper, wax coated paper, and glossy paper, as well as for high printing glossiness paper and paperboard samples and high glossiness ink paints;
45The glossiness measurement method is mainly suitable for measuring metal composite paper and paperboard such as aluminum foil paper and vacuum aluminum coated paper;
60The glossiness measurement method is mainly applicable to various types of paper, coatings, paints, etc.

4、 Product performance characteristics
instrumentAdopting integrated technology of light, machine, and electricity, as well as microcomputer measurement and control, it has the function of statistical processing of test data, can print and output, and can measure the glossiness of various object surfaces.
1.The instrument has multiple incident reflection measurement angles (75 °20°60°/45°);
2.Use polished black glass as the gloss standard. Black glass material with a refractive index of 1.567 and an ideal smooth surface, with a glossiness of 100 (glossiness unit)
3.By using range extension technology, the instrument can measure the glossiness of any surface (from zero glossiness to ideal mirror finish).
4The instrument has a power-off memory function and can automatically print detection reports. Computer memory zeroing, sample numbering, statistical calculation, numerical display and printable report of measured values, average values, and statistical results.
