Qiwei WSB-3 Desktop Microcomputer Whiteness meter

Introduction

Qiwei WSB-3 Whiteness Meter is a desktop computer-based Whiteness Meter, among which WSB-3Y fluorescent Whiteness Meter can determine whether the sample contains fluorescent whitening agent. The Whiteness Meter is composed of light source, optical system, detection system, computer data processing and display system, etc. Using high-quality components, microcomputer configuration, stable performance, accurate measurement. The measurement range of WSB-3 Whiteness Meter is 0~199.9, and the opacity of thin sheet materials can be measured by using the illumination condition of d/0.

Standards

Qiwei WSB-3 Whiteness Meter is a standard Whiteness Meter, which is designed and developed in strict accordance with the standard light source and lighting conditions stipulated by the International Commission on Illumination CIE. Method for measuring whiteness of mineral products", GB8940.1 "Measurement method for whiteness of pulp", GB13025.2 "General test method for salt industry, determination of whiteness", GB12097 and other national standards.

Features

1. WSB-3 Whiteness Meter is equipped with microcomputer, touch keyboard, LCD backlight liquid crystal display.

2. Stable and accurate color measurement performance. Using CAD, it is easy to operate and can accurately measure the opacity of paper.

3. The modified color filter system adopted by the WSB-3 Whiteness Meter makes the overall spectral characteristics of the Whiteness Meter fully conform to the CIE standard observer response curve, and can accurately measure the ISO whiteness value.

4. The stability and reproducibility are very high, and the system drift error is completely eliminated. It has the function of data storage and query, and meets the requirements of GLP.

5. The Whiteness Meter adopts imported high-quality original components, with high efficiency, low circuit power consumption, reasonable and brief optical path design, and good reliability.

6. With automatic calibration, average measurement mode, data storage and query functions.

Principle

The WSB-3 Whiteness Meter uses the principle of photoelectric conversion and an analog-to-digital conversion circuit to measure the radiant brightness energy value of the white reflection on the surface of the sample. After signal amplification, A/D conversion, and data processing, it finally displays the corresponding whiteness value.

Precautions for use

1) WSB-3 Whiteness Meter is a measuring instrument, do not disassemble it at will.

2) It should be used in a Operating Environment without corrosive gas or vibration source.

3) During use, there must be no strong light source or strong magnetic field interference around, the air should be dry, and there should be no floating objects such as dust.

4) The sample to be tested must not fall into the measuring cylinder of the WSB-3 Whiteness Meter, so as not to be unable to adjust zero.

5) Optical components cannot be touched directly by hand.

6) The black tube and working whiteboard should be kept clean and free from contamination to avoid affecting accuracy.
