The LS193 is a hand-held gloss meter with a micro measuring aperture, designed especially for small, curved or hard-to-reach surfaces where conventional gloss meters won’t fit. It’s ideal for precision work on mini components, curved plastics, jewelry, narrow painted parts, etc., while still offering a wide measurement range (0–1000 GU) and professional performance.

✨ Main Features
🔍 Micro Measuring Aperture
The small 1.5 × 3 mm measuring spot allows precise gloss measurement on tiny parts, curved edges, or narrow surfaces that larger gloss meters can’t fit.
📈 Wide Gloss Range
Despite its small measuring spot, it measures from 0–1000 GU — suitable for low, medium, and high gloss surfaces.
🤖 Simple Operation
Normal mode: Place the meter on the surface; it automatically reads the gloss without pressing any buttons.
QC mode: Set upper/lower limits for automatic pass/fail quality checks — useful for batch measurements in production environments.
🌈 Accurate & Stable
Uses a D65 light source with photopic spectral response, improving accuracy on colored samples.
💻 PC Software Support
Connect to a Windows PC via USB to:
Collect and save measurement data.
Configure test parameters.
Generate & print detailed test reports.
Linshang’s software supports all their gloss meters, including LS193.
🧠 Temperature Compensation
Built-in temperature compensation helps ensure stable measurements over time across varying environments.
📦 Portable & Durable
Compact & lightweight (about 300 g).
Aluminum shell for durability and easy handling during field or lab work.
📜 Standards & Compliance
The LS193 meets key international and national gloss measurement standards, ensuring compatibility with industry practices:
ISO 2813, ISO 7668
ASTM D523, ASTM D2457
DIN 67530
GB/T 9754, GB/T 13891, GB/T 7706, GB/T 8807
Meets Grade 1 working machine requirements under JJG 696-2015 Verification Regulation for specular gloss meters.
🎯 Best Use Cases
The LS193 is especially useful when dealing with:
Small components & mini parts (e.g., plastics, jewelry).
Curved surfaces or edges that larger gloss meters can’t measure.
Precision QC checks in manufacturing with automated pass/fail evaluation.
Production lines needing compact, rugged measurement tools.
