Linshang LS172 45/0 Touchscreen Colorimeter

The Linshang LS172 is a 45/0 handheld colorimeter with a 3.5-inch IPS capacitive touchscreen, 8mm measuring aperture and integrated quality-control functions. It is designed for direct instrument operation when measuring printed paper, packaging and other flat materials where surface appearance forms part of the color evaluation.

Unlike app-dependent compact meters, the LS172 displays measurement results, color differences, spectral reflectance curves and pass/fail decisions directly on the instrument. Android, iOS and Windows software support adds centralized color-library management, online measurement and report generation.

Key Features

• 45/0 measurement geometry: Provides surface-color evaluation suited to printing, paper and other flat materials.
• 3.5-inch IPS touchscreen: Operate measurement, comparison and QC functions directly from the instrument.
• 400–700nm spectral range: Displays spectral reflectance information at 10nm intervals.
• 8mm measuring aperture: Supports repeatable positioning on suitable printed and manufactured samples.
• ΔE*ab≤0.03 repeatability: Provides repeatable data for batch inspection and color consistency control.
• Approximately 1s measurement: Enables rapid color inspection during production and incoming quality control.
• Expanded color parameters: Measure CIE color spaces together with whiteness, yellowness, HSL, HSV, ITA and spectral data.
• Spectral reflectance curves: Evaluate changes in hue, saturation and shade beyond a single color-difference value.
• Electronic color-card matching: Identify the three closest stored color codes with published matching accuracy above 90%.
• Industrial QC mode: Set a color-difference tolerance and display pass/fail, ΔL, Δa and Δb results.
• App and Windows software: Manage color data, perform online measurements and generate reports across mobile and PC workflows.
• Measurement locating plate: Improve alignment when repeatedly measuring the same sample area.
• Integrated calibration tile: Keep the white calibration reference protected in the instrument base.

Applications

• Paper and printing quality control
• Labels and packaging production
• Whiteness and yellowness evaluation
• Batch color inspection
• Color formulation and sample comparison
• Report-based production quality management

Why Choose the Linshang LS172?

Choose the LS172 when 45/0 geometry is required together with direct touchscreen operation, spectral curves and Windows reporting. It is better suited to structured production QC than an app-only pocket colorimeter and is particularly relevant to printing, paper and packaging workflows.
