Jinhuatester CHY-01 Benchtop Mechanical Thickness Gauge

Overview

The Jinhuatester CHY-01 Benchtop Mechanical Thickness Gauge is a precision-contact thickness measurement instrument engineered for high-reproducibility mechanical displacement sensing in quality control and R&D laboratories. It operates on the principle of controlled-force mechanical compression between a calibrated anvil and a vertically actuated measuring probe—complying with standardized contact-area and load specifications defined in ISO 4593, ASTM D6988, and GB/T 6672 for plastic film and sheet thickness evaluation. Unlike optical or ultrasonic methods, this gauge delivers direct, traceable dimensional data under defined pressure conditions, eliminating refractive index dependencies or surface reflectivity artifacts. Its rigid cast-aluminum frame, linear-motion guide system, and temperature-stabilized load cell architecture ensure long-term zero stability and minimal hysteresis across repeated cycles. Designed for routine use in ISO/IEC 17025-accredited testing environments, the CHY-01 supports both manual single-point verification and repeatable multi-location profiling when integrated with optional automated feeders.

Key Features

• Automated probe lift mechanism eliminates operator-induced preload variability and ensures consistent contact initiation across all measurements.
• Dual-mode contact area configuration (50 mm² for polymer films; 200 mm² for paper/board) enables compliance with material-specific test standards without hardware modification.
• Adjustable traverse speed (10 mm/min, user-tunable within mechanical limits) allows optimization for soft, compressible substrates versus rigid, low-deformation materials.
• Backlit 5.7-inch color LCD displays real-time displacement readings, statistical summaries (mean, max, min, standard deviation), and pass/fail status against user-defined tolerance bands.
• Integrated thermal micro-printer outputs timestamped reports including individual readings, batch statistics, operator ID, and environmental metadata (if logged externally).
• RS232 serial interface supports bidirectional communication with Windows-based host systems for raw data streaming, remote command execution (e.g., START, ZERO, PRINT), and firmware updates.
• Modular design permits field retrofitting of optional accessories—including programmable auto-feeder modules capable of sequential positioning across up to 10 predefined locations per sample.

Sample Compatibility & Compliance

The CHY-01 accommodates flat, non-porous specimens with maximum dimensions of 300 mm × 300 mm and minimum stiffness sufficient to resist buckling under applied load. Validated applications include polyethylene (PE), polypropylene (PP), PET, PVC, aluminum foil, copper foil, silicon wafers (≥200 µm thick), filter paper, kraft board, and laminated packaging substrates. For regulatory alignment, the instrument’s pressure calibration protocol adheres to ISO 2556 Annex B requirements for pneumatic/hydraulic force verification. When operated with certified gauge blocks and documented calibration records (traceable to NIM or equivalent national metrology institutes), measurement uncertainty budgets meet typical QA/QC acceptance criteria per ISO/IEC 17025 Clause 6.4. The system supports GLP-compliant audit trails when paired with validated third-party software that logs user actions, calibration events, and result modifications.

Software & Data Management

Optional PC-based software provides full data acquisition, visualization, and reporting functionality compliant with FDA 21 CFR Part 11 requirements when deployed with electronic signatures, audit logging, and role-based access controls. Raw measurement sequences are stored in CSV and XML formats for integration into LIMS or MES platforms. Statistical process control (SPC) tools include X-bar/R charts, capability indices (Cp/Cpk), and trend analysis over time-series batches. All exported reports embed instrument ID, firmware version, calibration due date, and environmental sensor inputs (ambient temperature/humidity, if connected). Data integrity safeguards include write-once storage options, checksum validation, and automatic backup to network drives.

Applications

• Quality assurance of extruded plastic films in packaging manufacturing lines.
• Thickness uniformity mapping of battery separator membranes for lithium-ion cell production.
• Incoming inspection of metallized foils used in flexible electronics substrates.
• Process validation of calendered paper products in pulp and paper mills.
• Research-grade dimensional characterization of thin-film coatings on semiconductor wafers.
• Regulatory submission support for medical device packaging per ISO 11607-1 Annex A.

FAQ

Is the CHY-01 compliant with international thickness measurement standards?
Yes—it meets mechanical design and operational requirements specified in ISO 4593 (plastics), ASTM D6988 (polymer films), and GB/T 6672 (Chinese national standard), particularly regarding contact area, applied pressure, and probe geometry.
Can the instrument measure curved or irregular surfaces?
No—the CHY-01 is strictly designed for flat, planar specimens. Curved or textured surfaces require alternative metrology solutions such as confocal chromatic displacement sensors or coordinate measuring machines.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration certificate referencing NIM-traceable gauge blocks, listing as-found/as-left values at three points across the 0–5 mm range, and indicating measurement uncertainty at k=2.
Is GMP/GLP validation support available?
Yes—validated IQ/OQ protocols, URS templates, and 21 CFR Part 11-compliant software packages are available upon request through authorized distributors.
How often should recalibration be performed?
Annual recalibration is recommended under normal usage; however, frequency must be justified by risk assessment per ISO/IEC 17025 Clause 6.4.3 and adjusted based on usage intensity, environmental conditions, and internal quality procedures.
