Overview
The Fangyuan Instruments DR6000 is a dual-principle, hand-held coating thickness gauge engineered for non-destructive measurement of non-conductive coatings on ferrous substrates (e.g., paint, enamel, plastic, rubber) and non-ferrous metallic coatings on non-ferrous substrates (e.g., anodized layers, chrome, zinc, cadmium). It operates simultaneously via magnetic induction (for steel and iron) and eddy current (for aluminum, copper, stainless steel, brass) principles—enabling rapid, repeatable thickness assessment across diverse industrial surface treatment processes. Designed to meet the practical metrology requirements of QC labs, field inspectors, and maintenance technicians, the DR6000 delivers stable performance under ambient workshop conditions without requiring temperature stabilization or external calibration fixtures.
Key Features
- Dual-sensor architecture: Integrated magnetic induction probe (for Fe substrates) and high-frequency eddy current probe (for non-Fe substrates), automatically recognized upon substrate contact
- Auto-substrate recognition: Intelligent sensor switching eliminates manual mode selection; real-time substrate type identification displayed on LCD
- Measurement range: 0–1250 µm (Fe); 0–1000 µm (non-Fe), with resolution of 0.1 µm below 100 µm and 1 µm above
- Calibration flexibility: Supports zero-point calibration on bare substrate and two-point calibration using certified foil standards (ISO 2808-compliant)
- Rugged IP64-rated housing: Sealed against dust and water splashes; reinforced rubber overmold for drop resistance up to 1.2 m
- On-device data management: Stores up to 1,000 readings with timestamp, substrate ID, and operator code (user-definable)
Sample Compatibility & Compliance
The DR6000 is validated for use on flat, curved (min. radius 15 mm), and slightly rough surfaces typical of fabricated metal parts, pipelines, structural steel, and automotive components. It complies with ISO 2178 (magnetic method), ISO 2360 (eddy current method), and ASTM B499 (standard test method for measurement of coating thicknesses by magnetic and eddy-current test methods). While not certified to GLP or FDA 21 CFR Part 11 out-of-the-box, its audit-ready calibration log and user-accessible calibration history support integration into GMP-aligned quality systems when paired with documented SOPs and traceable reference standards.
Software & Data Management
The DR6000 supports USB-C data export to Windows-based PC software (included), enabling batch export of measurement sets in CSV and PDF report formats. Software features include statistical analysis (mean, SD, min/max, Cp/Cpk), pass/fail threshold configuration per job, graphical trend plots, and customizable report templates compliant with internal QA documentation requirements. All calibration events—including date, technician ID, standard used, and deviation values—are permanently recorded in device memory and exported alongside measurement data to satisfy traceability requirements under ISO/IEC 17025 Clause 7.7.
Applications
- Quality control of galvanized steel sheets and structural members in metal fabrication and construction
- In-process verification of powder coating thickness on aluminum extrusions and automotive body panels
- Final inspection of epoxy, polyurethane, and fire-retardant intumescent coatings on offshore platforms and chemical plant piping
- Verification of electroplated zinc/nickel layers on fasteners and precision machined components
- Periodic thickness auditing during corrosion prevention maintenance programs in petrochemical and power generation facilities
- Calibration lab support for accredited testing per ISO/IEC 17025, including uncertainty estimation using Type A evaluation of repeated measurements
FAQ
Does the DR6000 require annual factory recalibration?
No—recalibration is user-performed using traceable shims or bare substrate reference samples. Annual verification against NIST-traceable standards is recommended but not mandatory unless specified by internal QA protocols.
Can it measure coatings on hot surfaces?
Operation is rated for ambient temperatures from 0 °C to 50 °C; substrate surface temperature must remain below 60 °C to avoid thermal drift and sensor damage.
Is the device compatible with third-party LIMS or MES systems?
Yes—CSV exports are structured for direct ingestion into common laboratory information management systems; custom API integration requires optional firmware upgrade (contact Fangyuan technical support).
What is the probe wear life expectancy under normal industrial use?
The tungsten-carbide tipped probe is rated for ≥50,000 measurements on moderately abrasive surfaces; replacement probes are available as service parts with individual calibration certificates.
