UNI-T UT 343D Coating Thickness Gauge

Dual-Technology Ferrous & Non-Ferrous Detection: Automatically identifies magnetic metal substrates (steel, iron) and non-magnetic metals (aluminum, brass) to measure paint, powder coating, or plating thickness non-destructively.

High-Precision Wide Measuring Range: Accurately measures coating thickness from 0um to 1250um (0 - 49.2 mil) with fine resolution (-+ 3% + 1um accuracy).

2.0-Inch Color TFT LCD Screen: Features a bright, multi-angle color LCD display with automatic screen rotation to easily read measurements from any angle or direction.

Audio & 3-Color LED Limit Alarm: Instant visual (Green/Red/Yellow LED) and audible limit alerts trigger when measured coating thickness falls outside preset upper or lower threshold limits.

Multi-Point Calibration & Data Storage: Supports zero-point and 2-point reference calibration using included calibration foils, with memory storage for up to 500 sets of measurement data logs.

USB Data Export & Analysis Software: Equipped with a Type-C USB interface for connecting to PC software, enabling real-time data analysis, graphing, and professional reporting.

Housing & Sensor Construction: High-impact, anti-slip ABS plastic body with a wear-resistant ruby-tipped sensor probe to prevent scratching delicate substrate surfaces.

Technical Specifications:

Measurement Range: 0um - 1250 um (0 - 49.2 mil).

Units of Measurement: Switchable between Micrometer (um) and Mil (mil).

Power Supply: Powered by 2 x 1.5V AA batteries.

Calibration & Usage Advice: Perform zero-point calibration on reference metal plates prior to critical testing to maintain maximum accuracy.

Maintenance & Cleaning: Keep the probe tip clean and free of metal filings or wet paint using a soft, dry microfiber cloth.

Essential Tool for Automotive & Quality Inspection Pros: Position as a must-have diagnostic tool for automotive paint shops, car appraisers, manufacturing QA, plating shops, and field corrosion inspectors.

Highlight Dual Substrate Sensing & Auto-Rotation: Emphasize its auto-detect ferrous/non-ferrous capability and 360-degree screen rotation as key usability advantages over basic thickness gauges.

Recommended Cross-Sell Add-ons: Pair with UNI-T LM 50A Laser Distance Meter 50M, ThermoPro TP30 Digital IR Thermometer (-50°C ~ 550°C), UNI-T UT 511 Insulation Resistance Tester (100V - 1000V), and DL8003 12-240V AC.DC digital test pen.
