The LS173 Portable Colorimeter is a handheld color measurement and color difference meter designed for accurate color control and comparison across a wide range of materials — including paints, metals, stones, ceramics, plastics, and more. It uses D/8° optical geometry with specular component included (SCI), which is a standard approach for consistent reflection measurement of most sample surfaces.
🔬 Key Features
📱 Touchscreen & Easy Operation
Large 3.5-inch IPS capacitive touch screen makes navigation and measurement easy without many physical buttons.
Intuitive interface lets you start a measurement with a tap, view results quickly, and compare colors effortlessly.
🎯 Color Measurement & Matching
Integrates multiple standard electronic color charts and can match the measured color to the 3 closest color codes (≈ 90 %+ accuracy).
Displays color deviation values (ΔL, Δa, Δb) to help with visual matching and correction decisions.
📏 Quality Control (QC) Functions
Supports settable color difference thresholds for fast QC testing.
Provides pass/fail results based on chosen ΔE formulas.
📊 Rich Color Data & Analysis
Reports in multiple color spaces: CIE Lab, LCh, Luv, Yxy, CMYK, RGB, YI-98, plus whiteness/yellowness and spectral reflectance curves.
Supports many color difference formulas, including ΔEab, ΔEuv, ΔE94, ΔEcmc (various weighting ratios), ΔE*00.
📁 Large Local Storage
Can store thousands of color entries and build personalized color databases, reducing the need to carry physical reference cards.
🔗 Connectivity & Software
Works with mobile app (Android/iOS) and PC software for online measurement, sharing, reporting, and database management.
🧰 Portable & Practical Design
Handheld, ergonomic form for easy use in the field or production line.
Comes with a measurement locating plate for precise alignment and a built-in calibration white tile so you don’t lose the calibration accessory.
