The WSB-3C Benchtop Whiteness Meter is designed for laboratory and quality-control testing of the whiteness of suitable white or near-white materials. It features a measuring range of 0.00–199.99, a blue-light whiteness formula (WB = R475), an LED light source, and a 30 mm measuring aperture.

For manufacturers, testing laboratories, and distributors, the instrument provides a practical way to compare whiteness readings between samples and monitor material consistency during incoming inspection, production checks, and finished-product quality control.

Typical evaluation targets may include paper and paperboard, flour and other suitable powders, ceramics, plastics, coatings, and selected textile materials. The appropriate test method depends on the material, sample condition, and the standard required by the buyer.

Before ordering, confirm that the instrument's measurement principle, aperture, calibration procedure, and applicable standards match your laboratory or production requirements.

01.

Introduction

This benchtop whiteness meter is a professional device dedicated to whiteness analysis. It delivers speedy and precise whiteness readings for a broad range of materials, including paper, fabrics, plastics, paints and food items.

The device features intuitive controls, so users can operate it without prior professional training. Its rapid detection capability effectively raises testing productivity in labs and production workshops. Additionally, it enables data saving and exporting, which facilitates quality file archiving and continuous monitoring of product whiteness variations.

Built with solid construction and excellent durability, the unit sustains outstanding accuracy throughout long-duration operation. It acts as a trustworthy tool for whiteness inspection in both research labs and manufacturing facilities.

One quality-control indicator for appropriate ceramic materials, mineral powders, plastic goods, and coatings is whiteness assessment. Readings for these materials may be impacted by the sample surface, particle dispersion, texture, gloss, and optical characteristics.

Establish a standardized sample preparation and measurement process and compare it to your internal reference technique before implementing the instrument for routine inspection. Before placing a bulk order, ask the supplier to ensure appropriateness for materials with unique optical properties.

Laboratories can verify instrument response and ensure consistency between measurement sessions with the aid of reference standards. The provided instrument configuration determines the precise calibration process and necessary accessories.

Subject to verification in the WSB-3C user manual, a typical calibration and routine-check workflow might comprise the following steps:

1. Get the instrument ready. Set it up on a clean, sturdy workbench and let it achieve the manual's operating state.

2. Examine the area being measured. Make sure there is no dust or residue on the reference surface or measurement aperture.

3. Get the designated reference standard ready. Only use the calibration tool or reference plate.

4. Execute the reference or zero check as directed. Instead of presuming that all whiteness meters utilize the same calibration procedure, refer to the instrument's handbook.

5. A control sample should be measured. Note the outcome and compare it to the accepted criteria set by the laboratory.

6. Keep a record of the check. In the laboratory's quality records, note the date, operator, reference-standard identification, and observed reading.

7. Checks should be repeated as needed. Determine the frequency in accordance with the internal quality-control system, test standard, and manual.

Please ask QiweiLab to confirm the standard accessories that come with the WSB-3C, such as whether a powder sample holder and working or reference white plates are included. Do not assume that a powder press or compaction device is standard equipment unless it is confirmed in the quotation.

1. Ensure Consistent Product Quality

It conducts precise whiteness detection to unify the color tone of raw materials and finished goods across batches, effectively preventing returns and customer disputes resulting from color discrepancies.

2. Optimize Testing Productivity

Swift detection and straightforward operation cut down testing time in laboratories and on production lines, lifting overall operational efficiency.

3. Facilitate Data Administration

Measured data can be easily stored and exported. This helps build complete quality archives and supports full tracking and in-depth analysis of product quality.

4. Cut Down Operational Risks & Expenses

Thanks to its great stability and rugged build, it needs fewer maintenance sessions and replacements. It also avoids material losses incurred by abnormal whiteness levels.

5. Fit Diverse Industrial Scenarios

Compatible with paper, textiles, plastics, coatings, food and other materials, it fully meets the varied quality control needs of different businesses.

6. Elevate Brand Image

Strict whiteness control keeps products uniform in appearance. This builds customers' trust in the visual presentation and overall quality of your goods, strengthening brand credibility.

1. Is a white calibration plate included with the WSB-3C whiteness meter?

The product configuration and quotation determine the accessories that are provided. Please check with QiweiLab if the standard package includes a reference standard or white calibration plate. When obtaining a quote, please include the necessary testing procedure if your laboratory needs a particular reference standard.

2. Does the WSB-3C come with a sample grinder for flour or powder testing?

When a particular sample preparation technique calls for it, a sample grinder is utilized to lower or standardize particle size. It should not be taken for granted that the WSB-3C comes with it. If your testing process calls for grinding, please verify the standard packing list and inquire with QiweiLab regarding appropriate sample preparation tools.

3. Do I need a powder press or sample compaction device for flour whiteness testing?

Not all powder testing techniques call for the same equipment for preparation. To create a uniform measurement surface, a sample dish, leveling tool, or compaction equipment may be required, depending on the applicable standard. Before placing an order, please validate the necessary accessories by sharing your material type and test technique.

4. What information should I provide when requesting a quotation?

Please supply the substance to be tested, the necessary test standard, the anticipated sample form, the necessary accessories, the estimated order quantity, and your destination country in order to assist in determining an appropriate configuration. QiweiLab can then confirm the available configuration and quotation details.

5. Can I request a datasheet and a list of available accessories before purchasing?

Yes. Contact QiweiLab to request the brand new WSB-3C datasheet and verify the reachable accessories, such as reference requirements and pattern education equipment. Please specify whether or not your software entails paper, flour, ceramics, or any other cloth so the applicable statistics can be provided.
