The LS172 is a handheld portable colorimeter designed for accurate color measurement, color matching, and color difference quality control across a range of materials (printing, packaging, paint/coating, plastics, textiles, etc.).
🔬 Key Features
📲 Smart Touchscreen Interface
Equipped with a 3.5-inch capacitive IPS touchscreen for easy, intuitive operation without needing many physical buttons.
🎨 Multi-Color Charts & Quick Matching
Built-in multiple standard electronic color charts — the device can quickly match a measured color to the three closest color codes (~90% accuracy).
📊 Detailed Color Analysis
Displays CIE Lab color deviation values (ΔL, Δa, Δb) to help with color correction and mixing decisions.
📱 App & Software Connectivity
Works with a mobile app (Android & iOS) and PC software, allowing data export, report generation, and color database management.
✅ Quality Control Mode
You can set color difference thresholds and choose from multiple ΔE formulas for QC pass/fail testing.
📦 Includes Locating Plate
Comes with a measurement positioning plate for consistent sample alignment and more accurate readings.

🧠Main Uses
This model is ideal for color measurement and assessment tasks like:
Color quality control in production (e.g., printing, plastics, coatings)
Color matching against reference cards without manual comparison
Batch QC testing with pass/fail thresholds
It’s a versatile tool for anyone needing repeatable, standardized color data without a large benchtop spectrophotometer.
