Defelsko PosiTector 6000 Electromagnetic & Eddy Current Coating Thickness Gauge

Overview

The Defelsko PosiTector 6000 is a high-precision, dual-technology coating thickness gauge engineered for reliable non-destructive measurement of non-conductive coatings on conductive substrates. It integrates two fundamental physical principles: magnetic induction (for ferrous substrates such as steel and iron) and eddy current (for non-ferrous substrates including aluminum, copper, and austenitic stainless steel). This dual-sensor architecture enables consistent, traceable thickness measurements across diverse industrial applications—from automotive OEM finishing lines and marine corrosion control to aerospace component qualification and infrastructure maintenance. Each instrument is supplied with a NIST-traceable calibration certificate and incorporates real-time temperature compensation to minimize thermal drift—critical for field use where ambient conditions vary significantly. Designed to meet the metrological rigor required in quality assurance environments, the PosiTector 6000 conforms to ASTM D7091 (Standard Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonconductive Coatings Applied to Non-Ferrous Metals) and ISO 2178 / ISO 2360, ensuring compatibility with globally recognized QA/QC protocols.

Key Features

• Three configurable models: Basic (direct-read only), Statistics (250-reading memory, statistical summary, audible/visual out-of-tolerance alerts), and Storage (10,000-readings across 1,000 groups, built-in real-time clock, SSPC-PA2-compliant averaging)
• Dual-probe compatibility: F-probe for coatings on ferrous metals (e.g., paint, enamel, zinc on steel); N-probe for coatings on non-ferrous metals (e.g., anodize, powder coat on aluminum); FN-probe automatically detects substrate type and selects appropriate measurement mode
• Ruggedized industrial design: IP5X-rated enclosure; chemical-resistant, scratch-resistant LCD display; over-molded rubber bumper for drop protection; resistance to oils, solvents, acids, and dust
• Intuitive single-hand operation: tactile menu navigation, LED status lighting for measurement confirmation, instant factory reset function
• High-resolution display mode for enhanced readability of fine thickness increments; seamless metric–imperial unit conversion; multi-language interface (English, Chinese, Spanish, German, French)
• Expandable connectivity: integrated USB 2.0 port and infrared transceiver for data transfer; optional extended probe cables up to 75 meters for hard-to-reach or hazardous locations

Sample Compatibility & Compliance

The PosiTector 6000 supports measurement of non-conductive coatings—including paints, lacquers, epoxies, plastics, enamels, anodized layers, and ceramic coatings—on metallic substrates meeting minimum conductivity and permeability thresholds. Substrate thickness must exceed critical depth (typically ≥1 mm for ferrous, ≥0.5 mm for non-ferrous) to avoid base-metal interference. The instrument complies with ASTM D7091 Type I (magnetic induction) and Type II (eddy current), ISO 2178 (magnetic method), ISO 2360 (eddy current method), and SSPC-PA2 for statistical coating thickness verification in protective coating inspection. Its calibration protocol aligns with ISO/IEC 17025 requirements for accredited laboratories, and its data integrity features—including timestamped records and audit-ready export formats—support GLP and GMP documentation workflows.

Software & Data Management

PosiSoft for Windows—supplied standard with the Storage model—is a validated desktop application designed for post-acquisition analysis, reporting, and archival of coating thickness data. It imports ASCII-formatted files directly from the instrument via USB or infrared, enabling full traceability of each reading’s date/time stamp, probe ID, substrate type, and user-defined annotations. Users can generate statistical summaries (mean, standard deviation, Cp/Cpk indices), visualize trends via X-bar/R charts, annotate measurement locations on imported images, and export reports in PDF, CSV, or Excel-compatible formats. All calibration steps—including zero, one-point, and two-point procedures—are documented within the software, supporting FDA 21 CFR Part 11 compliance when configured with electronic signatures and audit trail logging.

Applications

• Aerospace: Verification of primer, topcoat, and thermal barrier coatings on aluminum airframes and titanium components
• Automotive: In-line QC of e-coat, basecoat, and clearcoat thickness on stamped steel and cast aluminum parts
• Marine & Offshore: Inspection of anti-corrosion coatings (zinc-rich primers, epoxy mastic) on ship hulls, pipelines, and FPSO structures
• Energy Infrastructure: Monitoring of internal lining thickness in oil/gas transmission pipelines and storage tanks
• Architectural Metalwork: Validation of anodized film thickness per AA-M102 and AAMA 611 specifications
• Manufacturing QA Labs: Routine calibration verification, process capability studies (Cp/Cpk), and supplier audit preparation
