Overview
The LABO LB-48A Colorimeter is a professional instrument for measuring the whiteness, yellowness, Color and color difference of objects, as well as the Opacity, transparency, light scattering coefficient, light absorption coefficient and inks absorption values of paper.
Features
1. Instrument Appearance Novel Compact Structure, Professional Circuit Design Ensure Precision and Stability of Measurement Data
2. Adopt CIE 1964 to supplement the chroma system and CIE 1976 (L * a * b *) color space Color difference formula
3. Geometry conditions of d/o illumination observation, diffuse ball diameter 150mm, test hole diameter 30mm, equipped with light absorber to eliminate the influence of specular reflection of the sample
4. Large screen high pixel LCD module, Chinese display operation steps and measurement results
5. Equipped with imported thermal printing movement, no noise and fast printing speed
6. Equipped with a standard RS232 interface, it can communicate with microcomputer software
7. The instrument has power-off protection function, and the calibrated data will not be lost after power-off
8. Can store 9 reference samples
Principle
The instrument simulates the illumination of the D65 illuminator, and uses the CIE 1964 supplementary chroma system and the CIE 1976 (L * a * b *) color space Color difference formula for measurement and analysis.
Applications
Papermaking, printing, Spinning & weaving
Standards
ISO 2469、ISO 2470、ISO 2471、ISO 9416、ISO 11475、GB/T 7973、GB/T 7974、GB/T 7975、GB/T 2679、GB/T 1543、GB/T 10339、GB/T 12911、GB/T 22880、GB/T 9338
Notice
• The size of the sample requires that the test plane be not less than φ 30mm and the thickness not exceed 40mm.
• Power supply voltage requirements AC220V +/- 22V 50Hz 0.5A, should be reliably grounded
• The service life of Chinese measurement and control LCD screen is about 50,000 hours
