Drick DRK508 Electronic Bottle Wall Thickness Gauge

Overview

The Drick DRK508 Electronic Bottle Wall Thickness Gauge is a precision metrology instrument engineered for non-destructive, contact-based thickness measurement of thermoplastic and glass containers used in beverage, pharmaceutical, and packaging industries. It operates on the principle of high-resolution linear displacement sensing—utilizing dual synchronized LVDT (Linear Variable Differential Transformer) probes to capture absolute wall thickness at discrete axial and circumferential positions. Unlike optical or ultrasonic methods, this mechanical contact system delivers direct, traceable dimensional data compliant with physical gauge calibration standards. Designed specifically for cylindrical hollow containers—including PET carbonated soft drink bottles, HDPE mineral water bottles, glass beer bottles, and pharmaceutical vials—the DRK508 enables quantitative assessment of wall uniformity, bottom crown geometry, and sidewall tapering critical to pressure resistance, sterilization integrity, and regulatory compliance.

Key Features

• Dual independent high-precision displacement sensors with 0.001 mm resolution and ≤±0.001 mm repeatability across full 25 mm range
• Real-time thickness curve visualization on integrated 5.7-inch monochrome LCD display, showing thickness vs. height profile during continuous scanning
• Automated data logging with user-definable sampling interval (1–50 mm/point); stores ≥100 complete measurement sets onboard
• Built-in thermal micro-printer for immediate hardcopy output of max/min/thickness ratio, mean deviation, and full profile snapshot
• USB 2.0 interface enabling bidirectional communication with Windows-based Drick Thickness Analysis Software (v3.2+)
• Modular probe rod system supporting rapid reconfiguration for base dome, sidewall, shoulder, and neck measurements across bottle types
• Robust aluminum alloy frame with vibration-damped base; calibrated per ISO 9001-certified internal procedures traceable to NIM (National Institute of Metrology, China)

Sample Compatibility & Compliance

The DRK508 accommodates container diameters from 10 mm (e.g., small ampoules) to 120 mm (large juice jugs) and heights up to 320 mm—covering standard 250 mL to 2 L PET bottles, 330 mL glass beer bottles, 10–100 mL pharmaceutical vials, and blow-molded HDPE pharmaceutical containers. Its mechanical probing methodology ensures reliable readings on opaque, colored, or textured surfaces where optical systems fail. The instrument conforms to multiple national and industry-specific standards: GB/T 2639–2014 (glass pharmaceutical containers), GB/T 2641–2010 (aluminum caps), GB/T 12415–2010 (sterile pharmaceutical packaging), and YBB series standards issued by the Center for Drug Evaluation (CDE), National Medical Products Administration (NMPA). While not inherently 21 CFR Part 11 compliant, audit-ready data export (CSV, PDF, XML) and electronic signature support are enabled via optional software license.

Software & Data Management

Drick Thickness Analysis Software (included) provides comprehensive post-acquisition processing: overlay comparison of multiple profiles, statistical process control (SPC) charting (X̄–R, Cp/Cpk), thickness deviation heatmaps, and automated pass/fail flagging against user-defined upper/lower specification limits (USL/LSL). All raw sensor timestamps, probe position coordinates, and environmental metadata (operator ID, date/time, sample ID) are embedded in exported files. The software supports GLP-compliant audit trails when deployed on validated Windows workstations; data integrity is preserved through SHA-256 hashing of measurement archives. Export formats include CSV (for Excel/Minitab), PDF reports (with calibration certificate reference), and XML (for LIMS integration).

Applications

• Quality assurance of PET bottle wall distribution during blow molding process validation
• Pharmaceutical primary packaging qualification per USP and EP 3.2.1 for glass vial bottom thickness consistency
• Root cause analysis of container collapse under autoclave pressure or carbonation stress
• Supplier qualification testing for contract packaging organizations (CPOs)
• R&D evaluation of recycled resin impact on wall homogeneity in sustainable packaging development
• Regulatory submission support for DMF (Drug Master File) and CMC (Chemistry, Manufacturing, and Controls) documentation

FAQ

Is the DRK508 suitable for measuring glass bottle thickness?
Yes—the dual-contact probe design eliminates interference from surface reflectivity or transparency, making it equally effective on soda-lime glass, borosilicate vials, and coated PET.
Can measurement data be integrated into an existing MES or LIMS?
Yes—via CSV/XML export and optional OPC UA gateway module (sold separately), enabling direct ingestion into Siemens Opcenter, Thermo Fisher SampleManager, or LabVantage platforms.
What calibration standards accompany the instrument?
Each unit ships with NIST-traceable stainless steel gauge blocks (1.000 mm, 5.000 mm, 10.000 mm) and a full calibration certificate issued by Drick’s ISO/IEC 17025-accredited metrology lab.
Does the system support GMP-compliant operation?
When used with validated software configuration, electronic signatures, and controlled access protocols, the DRK508 meets core Annex 11 and ALCOA+ data integrity requirements for pharmaceutical manufacturing environments.
Are custom probe fixtures available for irregular-shaped containers?
Yes—Drick offers OEM engineering services for bespoke probe mounts, vacuum chucks, and rotary indexing stages for oval, square, or multi-contoured containers upon request.
