Overview
The Fangyuan DR380 Coating Thickness Gauge is a dual-mode (magnetic induction and eddy current) portable instrument engineered for non-destructive measurement of non-magnetic coatings on ferrous substrates (e.g., zinc, epoxy, polyurethane, enamel) and non-conductive coatings on non-ferrous metals (e.g., anodized aluminum, chrome-plated copper). It operates in strict accordance with ISO 2178 (magnetic method), ISO 2360 (eddy current method), ASTM B499, and DIN EN ISO 1461 for galvanized steel inspection. Designed for field and shop-floor use, the DR380 delivers repeatable thickness readings across industrial surfaces with curvature, roughness, or minor contamination—without requiring zero calibration on every substrate. Its compact ergonomic housing, IP65-rated enclosure, and auto-ranging sensor ensure operational reliability in automotive refinishing, structural steel fabrication, pipeline corrosion control, and aerospace component QA.
Key Features
- Dual-sensor architecture: Integrated magnetic induction probe (for Fe substrates) and high-frequency eddy current probe (for non-Fe substrates), both factory-calibrated and user-verifiable via certified foil standards
- Measurement range: 0–1250 µm (Fe mode); 0–1000 µm (non-Fe mode), with resolution of 0.1 µm below 100 µm and 1 µm above
- Auto-substrate recognition: Intelligent detection of base material type (steel vs. aluminum/copper) eliminates manual mode switching errors
- Temperature-compensated electronics: Maintains accuracy across –10 °C to 50 °C ambient conditions, critical for outdoor infrastructure inspections
- Onboard statistical functions: Stores up to 2,000 data points with min/max/avg/SD calculation per batch; supports pass/fail threshold alerts based on specification limits
- Rechargeable Li-ion battery: 20+ hours continuous operation; USB-C interface for firmware updates and data export
Sample Compatibility & Compliance
The DR380 is validated for use on coated carbon steel, galvanized steel (hot-dip and electrogalvanized), stainless steel (ferritic grades), aluminum alloys (including 6061 and 7075), copper, brass, and titanium. It measures organic coatings (paints, primers, powder coats), metallic coatings (zinc, cadmium, nickel), and ceramic-based thermal barrier layers. All measurements comply with ISO/IEC 17025 traceability requirements when used with NIST-traceable calibration foils (e.g., Fischer FISCHERSCOPE® reference standards). The device meets CE marking directives (EMC 2014/30/EU, RoHS 2011/65/EU) and supports GLP-compliant documentation through timestamped CSV export.
Software & Data Management
The DR380 interfaces with Fangyuan’s PC-based DataLink Pro software (Windows 10/11 compatible) via USB or Bluetooth 5.0. Software features include customizable report templates (PDF/Excel), multi-batch comparison charts, SPC control chart generation (X-bar/R), and audit trail logging compliant with FDA 21 CFR Part 11 requirements (user authentication, electronic signatures, immutable records). Raw measurement files include metadata: date/time, operator ID, probe serial number, substrate type, temperature, and calibration verification status—enabling full traceability in regulated manufacturing environments.
Applications
- Automotive: Verification of OEM and refinish paint film build (primer, basecoat, clearcoat) on stamped body panels and chassis components
- Corrosion engineering: Quantification of hot-dip galvanizing thickness on transmission towers, bridge girders, and offshore platform structures per ASTM A123 and ISO 1461
- Oil & gas: Inspection of fusion-bonded epoxy (FBE) and 3LPE coating integrity on pipeline joints and fittings
- Aerospace MRO: Thickness verification of chromate conversion coatings and primer systems on aluminum airframe parts per AMS 2400 and Boeing D6-17487
- Electronics: Measurement of conformal coatings (acrylic, silicone, urethane) on PCB assemblies per IPC-CC-830
FAQ
Does the DR380 require daily recalibration?
No—factory calibration remains stable for 12 months under normal use. Daily verification using certified zero and span foils (supplied) is recommended per ISO 2178 Annex B.
Can it measure coatings on curved surfaces like pipes or bolts?
Yes—the probe’s 3-mm diameter contact surface and adaptive lift-off compensation enable accurate readings on radii ≥5 mm without fixture dependency.
Is the device suitable for measuring zinc coatings on sandblasted steel?
Yes, provided surface profile (Ra) does not exceed 50 µm; excessive roughness may require averaging ≥10 readings per location per ISO 19840.
Does the software support automated report generation for ISO 9001 internal audits?
Yes—DataLink Pro includes preconfigured templates aligned with ISO 9001:2015 clause 8.2.4 (monitoring and measurement resources) and generates revision-controlled PDF reports with embedded digital signatures.
What is the warranty and service coverage?
Two-year limited warranty covering parts and labor; global service network with authorized calibration centers in Germany, USA, Singapore, and Shanghai offering ISO/IEC 17025-certified recalibration.
