Overview
The Drick DRK203C High-Precision Mechanical Contact Thickness Gauge is an ISO- and ASTM-compliant laboratory instrument engineered for repeatable, traceable thickness measurement of planar thin materials under controlled mechanical loading conditions. It operates on the principle of direct mechanical displacement sensing using a calibrated spring-loaded probe with defined contact geometry and standardized applied pressure—ensuring compliance with the fundamental metrological requirements of contact-based thickness determination per GB/T 6672 and ASTM D645. Designed specifically for quality control laboratories in packaging, flexible electronics, battery separator manufacturing, and precision foil production, the DRK203C delivers high reproducibility across low-stiffness substrates including polymeric films (e.g., PET, BOPP, PE), metal foils (Al, Cu), silicon wafers (up to 3 mm thickness), and laminated barrier structures. Its rigid base frame, linear guide system, and temperature-stable aluminum alloy housing minimize thermal drift and mechanical hysteresis—critical for achieving Class 1 accuracy (per GB/T 6672) over extended operational cycles.
Key Features
- Motorized probe lift mechanism with programmable descent speed (0.5–3 mm/s) and auto-stop on contact detection
- Standardized contact area of Ø6 mm (28.3 mm²) and nominal contact pressure of 20 kPa—fully aligned with GB/T 6672 and ASTM D645 test protocols
- Real-time digital display showing instantaneous thickness, plus automatic calculation of max, min, mean, and standard deviation across user-defined test sets (n = 1–99)
- Integrated thermal-compensated linear encoder with 0.1 µm resolution and full-scale linearity error < ±0.5 µm
- Onboard statistical engine supporting Cp/Cpk calculation, histogram generation, and pass/fail threshold alerting
- Calibration traceability via certified stainless-steel reference blocks (included), with dual-point verification capability (0 mm and 1.000 mm)
- RS-232 interface for external data logging and optional Ethernet module for networked lab integration
Sample Compatibility & Compliance
The DRK203C accommodates flat, non-porous specimens up to 300 mm × 300 mm in footprint and 3 mm in maximum thickness. It is validated for use with plastic films (≥12 µm), metallized foils, paperboard laminates, ceramic substrates, and battery-grade microporous separators. All mechanical and procedural parameters adhere strictly to national and international standards: GB/T 6672 (plastic film thickness), GB/T 451.3 (paper and board), GB/T 6547 (corrugated board), ASTM D645 (standard test method for thickness of solid electrical insulating materials), ASTM D374 (dielectric thickness), and ASTM D1777 (textile foil thickness). The instrument’s mechanical design satisfies GLP documentation requirements—including audit-trail-capable calibration logs and operator ID tagging when connected to compliant LIMS platforms.
Software & Data Management
The DRK203C supports optional PC-based software (DRK-ThickSuite v3.2) enabling full 21 CFR Part 11 compliance through electronic signatures, role-based access control, and immutable audit trails for all measurement sessions, calibration events, and parameter changes. Raw data export is available in CSV, XLSX, and PDF report formats—with configurable templates aligned to internal QA workflows or customer-specific submission requirements. Batch-level metadata (sample ID, lot number, operator, environmental conditions) is captured at acquisition and embedded in exported files. Firmware updates are delivered via signed binary packages with SHA-256 checksum validation to ensure integrity and regulatory acceptability.
Applications
- QC release testing of roll-to-roll extruded polymer films in packaging converters
- Thickness uniformity mapping of anode/cathode foils prior to electrode calendering in Li-ion battery production
- Validation of coating thickness consistency on metallized PET carrier films
- Incoming inspection of semiconductor-grade silicon wafers and sapphire substrates
- Process capability analysis (Cp/Cpk) during slitting and rewinding operations
- Supporting ISO 9001:2015 clause 8.5.1 (control of production and service provision) and IATF 16949 section 8.5.1.1 (control plan implementation)
FAQ
What standards does the DRK203C comply with for thickness measurement?
It conforms to GB/T 6672, GB/T 451.3, GB/T 6547, ASTM D645, ASTM D374, and ASTM D1777—covering plastics, paper, board, electrical insulation, and metallic foils.
Is the probe contact pressure adjustable?
No—the probe applies a fixed, standardized pressure of 20 kPa per GB/T 6672; alternative pressure configurations require factory recalibration and custom probe assembly.
Can the DRK203C measure curved or textured surfaces?
It is designed exclusively for flat, rigid-to-semi-rigid planar specimens; concave/convex geometries or surface roughness > Ra 0.8 µm will compromise measurement validity.
How is traceability maintained for calibration?
Each unit ships with NIST-traceable stainless-steel reference blocks (0 mm and 1.000 mm); calibration certificates include uncertainty budgets per ISO/IEC 17025:2017 Annex A.
Does the instrument support automated reporting for ISO/IEC 17025 accredited labs?
Yes—when used with DRK-ThickSuite v3.2 and configured with digital signatures and audit logging, it fulfills reporting requirements for accredited testing laboratories.
