一、产品简介:

数显白度仪适用于白色和近白色物体或粉末表面的白度测量。可以准确地得出与视感度相一致的白度值。对于纸张的不透明度可以准确测量。本仪器可以广泛应用于纺织印染、油漆涂料、化工建材、纸张纸板、塑料制品、白色水泥、陶瓷、搪瓷、瓷土、滑石粉、淀粉、面粉、食盐、洗涤剂、化妆品等物体的白度测量。

Product introduction:

Digital whiteness meter is suitable for whiteness measurement of white and near-white objects or powder surfaces. The whiteness value can be accurately obtained in accordance with the visual sensitivity. The opacity of the paper can be accurately measured. This instrument can be widely used in whiteness measurement of textile printing and dyeing, paint coating, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, porcelain clay, talcum powder, starch, flour, salt, detergent, cosmetics and other objects.


二、工作原理:

★仪器利用光电转换原理,采用模数转换电路,将测量样品表面反射的辐亮度能量值,经信号放大、A/D转换,数据处理,A后显示出相应的白度值。

★仪器由光源、光学系统、探测系统、数据处理与显示系统等构成,总体白度值为蓝光度R457。定仪光谱漫反射击比均为1的理想表面的白度为100,光谱漫反射击比均为零的黑表面白度为0。

★本仪器完全按照国际照明委(CIE)规定的标准光源及照测条件而设计,通过严格检测、调试,并执行于企业标准Q/TDKY02-2004,可适用于GB2913、GB5950、GB8940.1、GB12097、GB13025.2等**标准。

Second, the working principle:

★ The instrument uses the principle of photoelectric conversion and adopts analog-to-digital conversion circuit to measure the radiance energy value reflected from the sample surface. After signal amplification, A / D conversion and data processing, the corresponding whiteness value is displayed after A.

★ The instrument is composed of light source, optical system, detection system, data processing and display system, etc. The overall whiteness value is blueness R457. The whiteness of an ideal surface with a spectroscopic diffuse reflectance ratio of 1 is 100, and the whiteness of a black surface with a spectral diffuse reflectance ratio of zero is 0.

★ This instrument is completely designed according to the standard light source and inspection conditions stipulated by the International Commission for Illumination (CIE). It has passed strict testing and debugging and is implemented in the enterprise standard Q / TDKY02-2004. It can be applied to GB2913, GB5950, GB8940.1, GB12097, GB13025.2 and other standards.
