Professional Digital Car Paint Thickness Gauge 0–2000µm – HW400S FE/NFE Tester with Backlit Display & Auto Calibration

The HW400S Digital Paint Thickness Gauge is built for accurate and non-destructive inspection of paint, metal coatings, and protective layers. It provides consistent measurements whether you’re checking vehicle paint integrity, assessing used-car repair history, or verifying industrial coating standards. Its compact form, high-precision sensor, and automatic substrate recognition make it suitable for both field use and controlled environments.

With a measurement range of 0–2000 µm and a fine resolution of 1 µm, the HW400S offers clear and reliable readings with minimal setup. The backlit LCD screen supports visibility in low-light conditions, while auto shutdown and battery indication help maintain efficiency during extended use.

Key Features & Benefits

1. High-accuracy measurement capability
   Measures coatings from 0 to 2000 µm with 1 µm resolution, enabling precise evaluation of paint thickness, clearcoat depth, and protective metal layers.
2. FE/NFE automatic substrate detection
   Quickly identifies whether the surface is ferrous (steel/iron) or non-ferrous (aluminum/copper) and applies suitable measurement mode. This is especially useful for mixed-material vehicle designs and layered industrial parts.
3. Non-destructive electromagnetic/eddy-current measurement
   Uses professional-grade technology to measure coatings without surface damage. This method is widely adopted in automotive detailing, body repair, industrial finishing, and quality-control procedures.
4. LCD backlight and power status indicator
   Ensures the screen remains easy to read in garage environments, inspection bays, warehouses, or outdoor settings. Battery alert prevents unexpected shutdowns during testing sessions.
5. Automatic shut-off for power saving
   Designed to preserve battery life and enhance operational safety, particularly during repeated testing or mobile inspections.
6. Portable and durable build
   Made from durable ABS material with a compact body (approx. 120 × 60 × 28 mm), making it easy to carry, operate, and store. Suitable for frequent use in workshops, research labs, and on-site inspections.
7. Wide application range
   Ideal for measurement of paint, chrome, enamel, galvanized layers, and anodized coatings across automotive, chemical processing, industrial manufacturing, and quality inspection environments.

Suitable Use Cases

• Vehicle inspection and paint authenticity checks – Useful for detecting repainted or repaired areas on used vehicles by identifying deviations from factory-standard coating thickness. This supports purchasing decisions and dealership verification.
• Automotive detailing and bodywork planning – Provides safe guidance before polishing, buffing, or sanding to avoid over-removal of clear coats or protective layers.
• Industrial and commercial surface inspection – Supports verification of powder-coating, plating, anodized finishes, and protective industrial layers, ensuring compliance with coating standards.
• Workshop, lab, and field environments – Stable and dependable performance under various temperature ranges, making it suitable for both controlled and outdoor testing conditions.

The HW400S coating gauge provides reliable measurement, broad material compatibility, and easy operation — making it a dependable tool for vehicle inspection, surface-treatment work, and coating-quality verification.
