Overview
The Jinhuatester DBH-01 Electronic Bottle & Preform Wall Thickness Gauge is a precision contact-type thickness measurement system engineered for non-destructive, high-repeatability evaluation of wall and base thickness in rigid primary packaging containers. It operates on capacitive grid (capacitance-based) sensing technology — a robust, drift-resistant method where two synchronized capacitive transducers (one stationary reference probe and one movable measuring stylus) generate differential capacitance signals proportional to the physical gap between them. As the stylus contacts the outer surface and the reference probe rests against the inner surface (or vice versa, depending on geometry), the system computes thickness in real time using calibrated signal conversion algorithms. This principle ensures stable performance across glass, PET, HDPE, and other thermoplastic bottle materials without requiring couplant or surface preparation. Designed specifically for regulated production and quality control environments, the DBH-01 delivers traceable, operator-independent measurements aligned with pharmaceutical packaging integrity requirements.
Key Features
- Adjustable vertical and radial sample stage accommodates bottles and preforms from φ20 mm to φ300 mm diameter and up to 350 mm height — supporting vials, ampoules, infusion bottles, cosmetic jars, and PET preforms.
- High-speed ARM Cortex-based embedded processor enables sub-100 ms per-point measurement cycle and real-time statistical calculation (mean, min, max, SD) for each test group.
- 7-inch TFT true-color touchscreen interface with intuitive icon-driven navigation; supports multi-language UI (English default) and on-screen calibration prompts.
- Onboard data management: stores up to 100 test groups (10 readings per group); all values timestamped and tagged with operator ID and batch code (via manual input).
- Integrated thermal printer outputs full measurement reports — including individual readings, statistics, date/time stamp, and instrument ID — compliant with basic GLP documentation needs.
- Optional PC software (supplied separately) enables unlimited data export (CSV, PDF), SPC charting, audit trail logging, and user permission levels — compatible with FDA 21 CFR Part 11-ready configurations when deployed with validated IT infrastructure.
Sample Compatibility & Compliance
The DBH-01 is validated for use with pharmaceutical-grade glass (Type I, II, III), borosilicate vials, molded PET preforms, HDPE cosmetic bottles, and aluminized plastic containers. Its mechanical design conforms to ISO 9001-aligned manufacturing practices and meets the dimensional and metrological criteria specified in Chinese Pharmacopoeia companion standards: YBB00332002–2015 (for glass container wall thickness), YBB00332003–2015 (for base thickness), and YBB00032004–2015 (for plastic container uniformity). It also satisfies legacy national standards GB 2639–1990 (glass bottle specifications), GB 2641–1990 (glass ampoule testing), and GB 12415–90 (sterile pharmaceutical packaging). While not intrinsically 21 CFR Part 11 certified, its optional software package supports electronic signature implementation, audit trail generation, and data integrity controls required under GMP Annex 11 and EU GDP guidelines.
Software & Data Management
The optional Windows-based DBH-Connect software provides extended functionality beyond onboard capabilities. It supports automated report generation per ASTM E29–23 (standard practice for using significant digits), customizable templates aligned with internal SOPs, and direct integration into LIMS via ODBC or CSV batch import. All raw data files are saved with immutable metadata (instrument serial number, firmware version, calibration date, operator login). The software enforces role-based access control (RBAC), session timeout, and electronic signature capture for critical actions such as calibration reset or result deletion — fulfilling core ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data governance principles. Audit logs record every data modification event with IP address, timestamp, and user context.
Applications
This gauge serves as a primary metrology tool in QC laboratories for incoming inspection of packaging components, in-process monitoring during blow molding or glass forming, and final release testing prior to sterilization or filling. Typical use cases include: verifying wall thickness uniformity in ISO-standardized 2R, 5R, and 10R vials; detecting localized thinning in PET preform shoulders prior to stretch-blow molding; validating base thickness consistency in parenteral glass containers to prevent breakage during lyophilization; and ensuring compliance with USP <660> and Ph. Eur. 3.2.1 glass container requirements. It is routinely deployed by contract manufacturing organizations (CMOs), regulatory agencies (e.g., provincial drug inspection institutes), and tier-1 packaging suppliers supplying global pharma brands.
FAQ
What measurement principle does the DBH-01 employ?
It uses dual capacitive grid sensors operating in differential mode to convert mechanical displacement into high-stability capacitance changes, enabling contact-based thickness determination without signal drift.
Is calibration traceable to national standards?
Yes — the instrument includes factory calibration certificates traceable to CNAS-accredited laboratories (certificate provided); users may perform field verification using NIST-traceable gauge blocks (optional accessory kit available).
Can the DBH-01 measure curved or tapered surfaces?
It is optimized for cylindrical and hemispherical geometries typical of bottle bodies and bases; concave/convex curvature within ±5° deviation from nominal radius is accommodated via automatic probe alignment compensation.
Does it support automated data export to ERP or MES systems?
Via the optional DBH-Connect software, yes — through configurable CSV/XML output paths, scheduled FTP transfers, or direct database write using secure ODBC drivers.
What maintenance is required for long-term accuracy?
Annual verification of probe parallelism and sensor linearity is recommended; stylus tips should be inspected weekly for wear or contamination, and cleaned with isopropyl alcohol before each shift.
