The LS216 is a multilayer ultrasonic thickness gauge made by Linshang Technology — a handheld precision measurement instrument that uses ultrasonic pulse-echo principles to measure the thickness of coatings and underlying materials accurately and non-destructively. 📏 Key Features & Capabilities 🔍 Multi-layer Thickness Measurement Can measure up to three layers at once (e.g., coating + intermediate layer + substrate). 📐 High Precision Resolution: Up to 1 μm. Accuracy: ≤ ±(3 %H + 3 μm), where H is the standard value. 🪶 Wide Measurement Range Coatings: ~13 – 5500 μm (epoxy, etc.). Metals (e.g., steel): ~300 – 14,800 μm. 🎛️ Adjustable Sound Velocity Supports 1000–9999 m/s sound velocity range, with multiple modes: preset materials, calculated from known thickness, or manual input. 📊 Visual Output 800×480 IPS color touchscreen with real-time waveform display to help verify and analyze measurements. 📏 Minimum Measuring Area & Usability Requires a small measurement spot (~Φ6 mm), great for tight or localized areas. 📦 Other Practical Features Built-in rechargeable battery (4000 mAh, USB-C charging). Stores up to 999 measurement sets. Temperature compensation for consistent results. Exportable data with accompanying PC software. 🛠️ How It Works The probe emits ultrasonic pulses into a material. When these pulses hit interfaces between different layers (e.g., coating vs substrate), part of the sound reflects back. The gauge measures the time it takes for the sound to return and calculates thickness based on sound velocity and time. 📊 Typical Applications The LS216 is suitable for: Coating thickness control (e.g., paint, epoxy). Quality inspection in manufacturing. Non-destructive testing for plastics, metals, glass, wood, composites. Industries like automotive, aerospace, shipbuilding, metallurgy, petroleum, and coatings quality control.
