Linshang LS172 Portable Colorimeter for Industrial Color Quality Control Malaysia
Introduction to Linshang LS172 Portable Colorimeter
Maintaining consistent product color is an important part of industrial quality control. Manufacturers in Malaysia need reliable color measurement methods to reduce production variation, improve product appearance and maintain customer specifications.
The Linshang LS172 Portable Colorimeter is a professional handheld color measurement instrument designed for objective color inspection. It helps quality control teams measure color values, compare samples against reference standards and evaluate color differences using numerical results.
With 45°/0° measurement geometry, a touchscreen interface and multiple color measurement functions, the LS172 provides a practical solution for industrial color quality control in Malaysia.
What Is the Linshang LS172 Colorimeter?
The Linshang LS172 is a portable colorimeter designed to measure surface color and quantify color differences between a reference sample and a test sample.
Instead of relying entirely on visual inspection, manufacturers can use the LS172 to obtain repeatable color measurements under controlled conditions.
Key Features of Linshang LS172
• 45°/0° optical measurement geometry
• 8 mm measurement aperture
• 3.5-inch touchscreen display
• Approximately 1-second measurement time
• CIE Lab and other supported color measurement spaces
• Delta E color difference evaluation
• Pass/Fail quality control function
• Electronic color chart matching
• Mobile application and Windows PC software support
These features make the LS172 useful for manufacturers seeking a portable solution for routine color inspection.
Why Industrial Color Quality Control Matters in Malaysia
Color inconsistency can create problems in manufacturing, particularly when products are produced in multiple batches or supplied to customers with specific appearance requirements.
A small change in raw materials, pigments, coating thickness or processing conditions can affect the final appearance of a product.
Common Color Quality Problems
• Different production batches showing inconsistent shades
• Plastic components not matching approved color samples
• Painted products showing visible color variation
• Packaging materials failing customer color requirements
• Supplier materials not matching approved reference standards
Using a portable colorimeter allows quality control personnel to compare measured color values rather than depending solely on individual visual judgment.
Understanding 45°/0° Color Measurement Geometry
The Linshang LS172 uses 45°/0° measurement geometry, in which illumination and viewing are arranged at defined angles.
This geometry is commonly used for appearance-oriented color evaluation. It is particularly relevant when manufacturers want to assess the visual color of suitable opaque surfaces under consistent measurement conditions.
However, surface texture, gloss, curvature and sample positioning can influence results. Users should follow a consistent measurement procedure and confirm that the instrument geometry is suitable for their materials.
Understanding CIE Lab and Delta E Color Difference
One of the important functions of a portable colorimeter is the ability to express color using numerical values.
CIE L*, a* and b* Values
• L* represents lightness, from dark to light.
• a* represents the green-to-red color axis.
• b* represents the blue-to-yellow color axis.
These values allow manufacturers to record and compare color measurements between reference and production samples.
What Is Delta E?
Delta E, commonly written as ΔE, is a numerical expression of color difference between two measured colors.
A lower Delta E generally indicates a smaller measured color difference under the selected formula. However, the acceptable tolerance depends on the material, customer specifications, measurement method and application.
Manufacturers should establish approved reference samples and suitable Delta E limits rather than assuming one tolerance is appropriate for every product.
Industrial Applications of Linshang LS172 in Malaysia
1. Plastic Manufacturing
Plastic injection moulding factories can use the LS172 to compare finished components against approved color samples. This helps identify shade differences caused by pigments, raw material variation or processing changes.
2. Paint and Coating Inspection
For suitable painted or coated surfaces, the LS172 can support routine color consistency checks. Operators can compare production samples against an approved master sample while maintaining consistent surface preparation and measurement conditions.
3. Printing and Packaging
Packaging manufacturers can use portable color measurement to evaluate color variation on suitable printed surfaces and packaging materials. For specialized print process control, users should also consider whether a spectrophotometer or densitometer is required.
4. Automotive Component Manufacturing
Automotive component suppliers may use the LS172 for comparative color inspection of suitable interior parts, plastic components and coated surfaces. Complex metallic or effect finishes may require specialized measurement equipment.
5. Incoming Material Inspection
Quality control teams can compare incoming material samples with approved references before releasing materials for production. This supports supplier consistency and reduces the risk of color-related production rejection.
How to Use Linshang LS172 for Color Quality Control
Step 1 - Prepare the Sample
Ensure the measurement surface is clean, dry and suitable for the instrument aperture. Avoid unstable positioning or uneven surfaces whenever possible.
Step 2 - Prepare the Instrument
Follow the manufacturer's operating instructions, including any required calibration or reference checks before measurement.
Step 3 - Measure the Reference Color
Measure an approved master sample and save or record the reference color values using the instrument's supported functions.
Step 4 - Measure the Production Sample
Place the instrument consistently against the production sample and obtain the measurement results. Multiple readings may be useful when surface variation is expected.
Step 5 - Compare Delta E Results
Compare the measured color difference against the tolerance established by the factory or customer.
Step 6 - Record the Inspection Result
Record the sample identification, reference standard, color difference formula, measured results and Pass/Fail decision where applicable.
Linshang LS172 vs Visual Color Inspection
Traditional visual inspection can be useful for identifying obvious color differences, but the results may vary with lighting conditions, observer perception and viewing environment.
The LS172 provides numerical color measurements that help standardize comparisons. Nevertheless, instrumental measurement and controlled visual evaluation can complement each other, especially for products where texture, gloss or special finishes affect perceived appearance.
Who Should Consider the Linshang LS172?
• Manufacturing quality control departments
• Plastic injection moulding companies
• Paint and coating manufacturers
• Packaging and printing businesses
• Automotive component suppliers
• Incoming material inspection teams
• Production engineers responsible for color consistency
The LS172 is particularly relevant to companies that require portable color comparison without immediately investing in more complex laboratory color measurement systems.
How to Choose the Right Colorimeter for Your Factory
Before purchasing a portable colorimeter, manufacturers should consider the material surface, measurement geometry, aperture size, required color difference formulas, data handling needs and customer inspection standards.
The LS172 uses 45°/0° geometry. Other instruments, including models using D/8 geometry, may be more suitable for certain materials or measurement requirements.
Choosing the correct geometry is important because readings from different instrument configurations may not be directly interchangeable.
