Whiteness meter supplier

1. Overview
The DH-WT digital whiteness meter can be applied to measure the whiteness of objects such as textile printing and dyeing, paint and coatings, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, porcelain clay, talcum powder, starch, flour, salt, detergents, cosmetics, etc.

The DH-WT digital whiteness meter consists of a light source, optical system, detection system, data processing and display system, etc. The overall whiteness value is blue light R457.

The whiteness of a surface with a spectral diffuse reflectance ratio of 1 is 100, and the whiteness of a black surface with a spectral diffuse reflectance ratio of 0 is 0.

The DH-WT digital whiteness meter is designed according to the lighting source and measurement conditions specified by the Commission on Illumination (CIE). Through strict testing and debugging, it can be applied to GB2913, GB5950, GB8940.1, GB12097, GB13025.2, etc.

2. Working principle

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

3. Purpose:

The DH-WT digital whiteness meter is mainly suitable for measuring the whiteness of white and near white objects or powder surfaces. It can obtain a whiteness value that is equal to the visual sensitivity. The opacity of paper can be accurately measured.

4. Functional Features

1. Low power configuration, compact and beautiful appearance design, easy to use in the field or laboratory.

2. Equipped with low voltage indicator, automatic shutdown, and low-power circuit, it can effectively extend the battery's usage time.

3. Adopting a large screen clear LCD display, it has comfortable reading and is not affected by natural light.

4. Using low drift integrated circuits and long-life light sources, the instrument can effectively operate stably for a long time.

5. Reasonable and concise optical path design can effectively measure the correctness and repeatability of values.

6. Simple operation can accurately measure the opacity of paper.
