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

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等国家标准。
Second, the working principle:
★The instrument uses the principle of photoelectric conversion, adopts the analog-to-digital conversion circuit, and measures the radiance energy value reflected on the surface of the sample, through signal amplification, A/D conversion, data processing, and finally displays the corresponding whiteness value.
★The instrument consists of light source, optical system, detection system, data processing and display system. The overall whiteness value is Blu-ray R457. The ideal surface of the spectroscopic diffuse reflectance ratio of 1 has a whiteness of 100, and the absolute black surface whiteness of the spectral diffuse reflectance is zero.
★ This instrument is designed according to the standard light source and lighting conditions specified by the International Commission on Illumination (CIE). It has passed strict inspection, debugging and implementation in the enterprise standard Q/TDKY02-2004, and can be applied to GB2913, GB5950, GB8940.1, National standards such as GB12097 and GB13025.2.
