Linshang LS172 45/0 Colorimeter with Touch Screen Malaysia

Introduction to Linshang LS172 45/0 Colorimeter

Accurate and consistent color measurement is essential for manufacturers that need to maintain product appearance across different production batches. In Malaysia, industries such as plastic manufacturing, coating, printing, packaging and automotive component production frequently require reliable color comparison methods.

The Linshang LS172 45/0 Colorimeter with Touch Screen is a portable color measurement instrument designed to help manufacturers evaluate surface color and compare production samples with approved references.

Featuring 45°/0° optical geometry, an 8 mm measurement aperture and a 3.5-inch touchscreen, the LS172 combines practical operation with numerical color measurement for industrial quality control.

What Does 45/0 Mean in a Colorimeter?

The term 45/0 refers to the optical geometry used during color measurement. In this arrangement, light illuminates the sample at approximately 45 degrees relative to the measurement axis, while reflected light is measured along the 0-degree viewing direction.

This configuration is commonly used when the objective is to evaluate the appearance-related color of suitable opaque surfaces under defined measurement conditions.

The optical arrangement is important because surface reflection depends not only on pigment or material color but also on surface texture, gloss and measurement direction.

Why Measurement Geometry Matters

• It establishes consistent illumination and observation conditions.

• It helps reduce variation caused by changing viewing angles.

• It supports repeatable color comparison when sample preparation and positioning are controlled.

• It allows manufacturers to establish a consistent measurement method for approved reference samples and production batches.

Measurements obtained using 45/0 geometry should not automatically be treated as interchangeable with readings from instruments using different optical geometries, such as D/8.

Advantages of 45/0 Geometry for Industrial Color Inspection

1. Appearance-Oriented Color Evaluation

The 45/0 configuration is relevant for applications where the visual appearance of a finished surface is important. Examples include suitable painted panels, plastic housings and printed materials.

However, special-effect coatings, highly textured surfaces and strongly directional materials may require additional measurement methods.

2. Consistent Reference Sample Comparison

Quality control teams can establish an approved reference sample and compare subsequent production samples using the same instrument, geometry and measurement procedure.

This helps reduce subjective differences between operators and supports documented inspection decisions.

3. Production Batch Monitoring

Factories can use numerical color measurements to monitor color variation between production batches. Unexpected changes can trigger further investigation into raw materials, pigments, processing conditions or finishing methods.

4. Supplier Quality Inspection

Incoming materials can be compared with approved references before production begins. This can help manufacturers identify color inconsistency at an earlier stage.

Linshang LS172 3.5-Inch Touch Screen Display

One of the practical features of the Linshang LS172 is its 3.5-inch touchscreen interface. A touchscreen can simplify access to measurement functions and make routine color inspection more convenient for production and quality control personnel.

Benefits of a Touchscreen Colorimeter

• Convenient access to supported color measurement functions.

• Clearer presentation of measurement results and color difference information.

• Practical operation during routine sample inspection.

• Reduced dependence on complicated physical button combinations.

• Suitable for repeated factory quality control workflows.

Operators should still receive basic training in reference sample selection, measurement positioning, tolerance settings and interpretation of results.

Understanding the 8 mm Measurement Aperture

The LS172 uses an 8 mm measurement aperture. The aperture defines the area of the sample being evaluated by the instrument.

For reliable measurements, the sample should provide sufficient flat, uniform measurement area to cover the aperture correctly.

Why Aperture Size Is Important

• The measured area should represent the actual product surface.

• Small patterns or mixed-color surfaces may produce results that depend on the exact measurement position.

• Curved or uneven components may not provide consistent instrument contact.

• Measurements near edges, holes or surface defects may not represent the intended sample color.

For very small components or complex shapes, manufacturers should confirm whether an 8 mm aperture is suitable before purchasing.

Fast Color Measurement for Factory Quality Control

The Linshang LS172 offers an approximately 1-second measurement time, making it practical for repeated sample checks during routine inspection.

Fast measurement is particularly useful when a factory needs to inspect multiple components or compare samples from different production batches.

However, overall inspection speed also depends on sample handling, reference selection, measurement positioning and recording requirements.

CIE Lab Color Measurement with Linshang LS172

The LS172 supports numerical color evaluation using CIE Lab and other supported color measurement functions.

Understanding L*, a* and b*

• L* indicates lightness, ranging from dark to light.

• a* describes the green-to-red color axis.

• b* describes the blue-to-yellow color axis.

These numerical values allow quality control personnel to document the measured color of an approved reference and compare it with production samples.

For example, if a plastic component becomes more yellow between batches, the measured color coordinates may help identify the direction of the change.

Delta E Color Difference Measurement

Delta E, written as ΔE, represents the numerical difference between two colors under a selected color difference formula.

The LS172 can support color difference evaluation for comparison between a reference sample and a test sample.

How Delta E Supports Quality Control

• Provides a numerical basis for comparing color samples.

• Supports batch-to-batch color consistency monitoring.

• Helps operators identify samples requiring further investigation.

• Can be used with approved acceptance tolerances for Pass/Fail inspection.

There is no single universal Delta E acceptance limit for every product. Suitable tolerances depend on the industry, surface finish, customer requirements, selected formula and measurement conditions.

For meaningful comparison, operators should consistently use the same color difference formula and documented measurement procedure.

Pass/Fail Color Quality Control

The Linshang LS172 includes a Pass/Fail function that can support routine quality control decisions based on configured color difference limits.

For example, a manufacturer may establish an approved reference sample and define an acceptable tolerance according to customer requirements.

A production sample can then be measured and evaluated against that established tolerance.

The instrument result supports the inspection process, but final product acceptance should also consider other relevant specifications, surface appearance requirements and customer quality procedures.

Industrial Applications of LS172 in Malaysia

Plastic Injection Moulding

Plastic manufacturers in Selangor, Johor and Penang can use the LS172 to compare suitable plastic components with approved master samples. This supports monitoring of pigment variation, batch consistency and supplier quality.

Paint and Coating Production

Coating manufacturers and quality control teams can evaluate color differences between suitable finished panels and reference standards. Consistent surface preparation is essential for meaningful results.

Printing and Packaging

Packaging manufacturers may use the LS172 for comparative inspection of suitable printed or coated surfaces. For detailed process-color control or spectral analysis, more specialized instruments may be necessary.

Automotive Plastic Components

Automotive suppliers can use the instrument to compare the color of suitable molded or finished components. Complex metallic, pearlescent or highly textured surfaces may require specialized measurement geometry.

Consumer Product Manufacturing

Manufacturers of appliance housings, electronic enclosures and consumer goods can use portable color measurement to support consistent appearance across production batches.

How to Measure Color Using Linshang LS172

Step 3 - Measure the Approved Reference

Use the LS172 to measure an approved master sample and record or save its color information using the supported instrument functions.

Step 4 - Measure the Test Sample

Position the instrument consistently against the test surface and perform the measurement. Take additional readings when sample variation makes them necessary.

Step 5 - Evaluate the Color Difference

Compare the measured Delta E result with the documented factory or customer tolerance.

Step 6 - Document the Inspection

Record the sample identity, measurement conditions, selected formula, reference information and acceptance decision.

45/0 Colorimeter vs D/8 Colorimeter

A 45/0 colorimeter and a D/8 colorimeter use different illumination and observation arrangements.

A 45/0 instrument is often selected for appearance-related color comparisons on suitable surfaces, while D/8 instruments use diffuse illumination and may offer different approaches to evaluating surface color and specular reflection, depending on the instrument configuration.

Neither geometry is universally better. The correct choice depends on the material, inspection objective, customer measurement standard and the need to match existing reference data.

Manufacturers should avoid directly comparing numerical results from different geometries without confirming method compatibility.

Is Linshang LS172 Suitable for Your Factory?

The LS172 may be a practical choice for manufacturers requiring portable color measurement, touchscreen operation, routine Delta E comparison and reference-based quality inspection.

Before purchasing, confirm the required measurement geometry, aperture suitability, color difference formula, software workflow and any applicable customer specifications.

If detailed spectral data, complex effect-finish evaluation or specialized industry compliance is required, a different instrument category may be more appropriate.
