Product Overview

Laboratory Digital Whiteness Meter

A laboratory digital whiteness meter is designed to quickly and accurately measure the whiteness of white or near-white surfaces. It is widely used for whiteness quality control in products such as flour, starch, paper, plastics, ceramics, coatings, textiles, table salt, detergents, and cosmetics.

Working Principle

The whiteness meter uses a semiconductor light source to emit blue light or simulated D65 illuminant light. An integrating sphere produces uniform, diffuse illumination that falls on the sample. The reflected light is detected by a silicon photocell and converted into an electrical signal. A microcomputer processes the signal and displays the whiteness value digitally. R457 blue-light whiteness is one of the commonly used measurement indices.

Applications

Laboratory whiteness meters are widely used in the paper, textile and dyeing, plastics, coatings, ceramics, building materials, food, chemical, and personal care industries. They are suitable for raw material inspection, production process control, finished product quality inspection, and laboratory research and development. They are particularly useful for quality management applications where consistent whiteness is essential.

Lab Whiteness Meter Selection Guide

When selecting a laboratory whiteness meter, several factors should be considered. A D/0 diffuse illumination and 0° viewing geometry is preferred where appropriate, as it helps reduce the influence of sample gloss and directional characteristics on measurement results. Key performance specifications include repeatability, indication error, and zero-point drift. Check whether the instrument supports multiple whiteness measurement formulas, including R457. Useful features may include one-touch zeroing, calibration with a standard white plate, data storage, an RS-232 interface, and a long-life semiconductor light source.

Portable Whiteness Meter

1. Operation panel

LCD liquid crystal display, reading display, with zero adjustment and correction functions.

2. Test hole

Using the 45/0 observation condition can eliminate the influence of the surface glossiness of the measured object on the whiteness value. It also effectively prevents light leakage from the measurement hole.

3. Comes with standard whiteboard

Work standard whiteboard*3 pieces

4. Accurate and reliable

Three whiteboards are provided as standard, and the national calibration whiteboard is used to transmit standard values and measure.

Simple operation and beautiful appearance design.

Low-drift high-precision integrated circuit, efficient and long-life light source can work stably for a long time.

Customer Photos/ Customer Review

The instrument can be used after simple calibration after receipt. The reading is stable and the accuracy is 0.1, which meets our powder testing requirements. The operation is not complicated and the daily detection efficiency is very high. If you have any operational questions, the customer service will respond quickly, the delivery speed is fast, and the price/performance ratio is good.

After continuous use for a period of time, the measurement is accurate, the reading response is rapid, and it is not easily disturbed by slight light in the environment. The measurement method complies with industry standards. Packed thickly for transportation without scratches or deformation, pre-sales customer service will give usage suggestions based on sample type.

The body is simple in workmanship, the large digital screen has intuitive readings, and the 0~100% range is fully covered. It can measure paper, calcium carbonate powder, and ceramic samples. Press down the measuring head to fit the sample without reflection, and the measurement speed is fast.

This digital display whiteness meter is really easy to use, the readings are intuitive, and the accuracy is sufficient. You no longer have to worry about estimation errors. Calibration is also convenient. If you calibrate before each measurement, the data will be very accurate. The blue light measurement method also meets the national standard requirements. The customer service responded in a timely manner and taught me how to calibrate and perform daily maintenance. The logistics was also fast and the goods arrived without any problems.
