Overview
The Infralytic NG2 Portable Infrared Oil Film Thickness Analyzer is an engineered solution for non-contact, real-time quantification of organic thin films on metallic substrates. Operating on the principle of near-infrared (NIR) absorption spectroscopy with interference-filter-based spectral discrimination, the NG2 isolates characteristic C–H stretching vibration bands (typically centered at ~1720–1740 cm⁻¹, corresponding to 5.75–5.85 µm wavelength) to determine coating mass per unit area. Unlike contact-based or gravimetric methods, this technique requires no solvent extraction, sample destruction, or calibration transfer between instruments — each measurement is traceable to factory-established reference standards validated against ASTM D7865 and ISO 9227-correlated corrosion performance data. Designed for integration into continuous coil processing lines and offline QC stations, the NG2 delivers laboratory-grade repeatability (±0.02 g/m² typical RSD < 2.5% across 5–30 g/m² range) in a field-deployable form factor.
Key Features
- Single-button operation with intuitive OLED display showing real-time thickness (g/m²), measurement status, battery level, and temperature compensation flag
- Integrated Peltier-stabilized detector ensuring thermal drift < 0.005 g/m²/°C over 10–40 °C ambient range
- Optical path optimized for high signal-to-noise ratio on reflective substrates: aluminum, cold-rolled steel, galvanized steel, and silicon electrical steel
- Auto-zero function compensates for substrate emissivity variations and surface roughness effects (Ra ≤ 1.6 µm)
- Ruggedized IP54-rated magnesium alloy housing with shock-absorbing silicone bumper; operational drop-tested from 1.2 m onto concrete
- Built-in memory stores up to 10,000 timestamped measurements with GPS-tagged location metadata (optional external module)
Sample Compatibility & Compliance
The NG2 is validated for quantitative analysis of hydrocarbon-based lubricants (e.g., mineral oils, ester blends), chromate and trivalent chromium passivation layers, polymeric fingerprint-resistant coatings (acrylic, silicone-modified resins), insulating varnishes on grain-oriented silicon steel (GOES), and epoxy-phenolic resin linings on aluminum beverage cans. It conforms to the physical measurement requirements of ISO 2808 (paints and varnishes — determination of film thickness), ASTM E1977 (standard guide for NIR quantitative analysis), and supports audit-ready documentation for IATF 16949-certified automotive suppliers. All factory calibrations are performed using NIST-traceable reference foils and certified oil-coated reference panels (certified by BAM, Berlin). The instrument’s firmware includes GLP-compliant user access control (three-tier password protection) and full 21 CFR Part 11–ready electronic signature capability when paired with optional Infralytic DataLink software.
Software & Data Management
The NG2 interfaces via USB-C or Bluetooth 5.0 to the Infralytic DataLink Suite (Windows 10/11 compatible), enabling batch export of .csv/.xlsx files with embedded metadata (operator ID, shift code, line number, substrate grade). Trend analysis tools generate X-bar/R charts aligned with SPC protocols, while deviation alerts trigger automatic flagging of out-of-spec readings relative to user-defined upper/lower control limits. Raw spectral logs (128-point absorbance vectors) are retained for retrospective reprocessing using updated chemometric models. Audit trails record every configuration change, calibration event, and data export action with immutable timestamps and operator identifiers — fully compliant with FDA-mandated data integrity principles (ALCOA+).
Applications
- Real-time monitoring of rolling oil distribution uniformity on cold-rolled steel coils prior to annealing
- Verification of chromate-free passivation layer mass on hot-dip galvanized (HDG) automotive body panels
- Quantitative control of insulating coating weight on transformer core laminations (M4–M6 grades)
- In-line verification of UV-curable fingerprint-resistant polymer thickness on pre-painted aluminum sheets
- End-of-line validation of internal can coating consistency for beverage container manufacturers (ISO 20573 compliance)
- Root-cause analysis of white rust formation on stored galvanized coils via correlation with localized oil depletion zones
FAQ
Does the NG2 require daily recalibration?
No — factory calibration remains stable for ≥12 months under normal operating conditions. A quick verification check using the supplied reference standard is recommended before each shift.
Can it measure on curved or textured surfaces?
Yes, provided curvature radius > 50 mm and surface roughness Ra ≤ 2.5 µm. Optional concave/convex optical adapters are available for radii down to 15 mm.
Is spectral library customization supported?
Yes — users may develop proprietary calibration models using the Infralytic ChemModel Studio, subject to validation per ISO/IEC 17025 guidelines.
What maintenance is required?
Annual performance verification by an Infralytic-certified service center; optical window cleaning with isopropyl alcohol and lint-free wipes after every 200 measurements.
How is temperature variation compensated during field use?
The integrated thermistor and dual-beam referencing system dynamically corrects for both ambient temperature shifts and substrate thermal emission fluctuations in real time.
