LS176 Spectrophotometer — Portable Handheld Spectrophotometer
A handheld multi-functional spectrophotometer and colorimeter designed for accurate color measurement, spectral analysis, and quality control across materials such as paints, coatings, plastics, stone, automotive finishes, leather, textiles, etc. It combines spectrophotometer-level color measurement with easy touchscreen operation and mobile/PC connectivity.
🔍 Key Features
🎨 Spectral Measurement & Reflectance Curves
Uses a full-spectrum LED light source for balanced illumination across the visible range.
Built-in advanced spectral sensor with curve-fitting algorithms gives professional spectral reflectance curves for deeper color analysis.
This means you can evaluate hue, saturation, and shade beyond just basic color numbers.
📏 D/8° Geometry (SCI)
Standard D/8° illumination with Specular Component Included (SCI) is widely used in industry to capture diffuse and specular-included color data for consistent, comparable results.
🖥️ Interactive Touchscreen
3.5″ IPS capacitive color touchscreen makes operation intuitive and standalone (no phone needed).
📊 Rich Color Space Support
Reports in many color spaces:
• CIE Lab, Luv, LCh, Yxy
• CMYK, RGB, Hex
• Whiteness & yellowness metrics (WI-98, Hunter, R457, YI-98)
• Spectral reflectance curves
🧮 Color Difference & QC Functions
Supports common ΔE formulas:
• ΔEab, ΔEuv, ΔE94, ΔEcmc, ΔE*00
— enabling robust color difference comparisons and QC thresholds.
📱 Connectivity & Software
Connects to a mobile app for color sharing and to PC software for deeper analysis, data import/export, and reporting.
🧠 Color Libraries & Matching
Includes multiple electronic color charts for quick matching — over ~90% matching accuracy.

🛠 Why This is Useful
Gives true spectrophotometric data instead of only tristimulus values — essential for industries needing consistent color quality across batches or materials.
Spectral reflectance curves help detect subtle differences in surface characteristics, gloss, or texture that color numbers alone might miss.
Portable form factor makes it practical for factory floor QC, field inspections, or production lines.
🛠 Typical Applications
✔ Automotive paint and coatings
✔ Decorative materials, plastics & hardware
✔ Textile, leather & upholstery
✔ Furniture and wood finishes
✔ Industrial quality control and inspection
