Overview
The WAYEAL ZH600-X Multi-Station Hermeticity Leak Detector is a helium mass spectrometer-based leak detection system engineered for high-throughput, quantitative integrity verification of sealed components in manufacturing and quality control environments. Unlike tracer-gas-independent pressure decay or differential pressure methods, the ZH600-X integrates a dedicated helium mass spectrometer (HMS) as its primary detection engine—leveraging the unique mass-to-charge ratio (m/z = 4) of helium ions to achieve sub-10⁻¹⁰ Pa·m³/s sensitivity under optimized vacuum conditions. The instrument operates in sniffer, hood, or vacuum chamber modes, with the ZH600-X variant specifically configured for multi-channel sequential or parallel testing of up to four independent sample stations (A/B/C/D), each programmable with discrete pressure profiles, dwell times, and pass/fail thresholds. Its architecture conforms to ISO 10648-2 (leak detection—terminology and classification) and supports traceable calibration protocols aligned with ASTM E493 and ISO 13302 standards for leak rate quantification.
Key Features
- Four independent test channels (A/B/C/D) with fully decoupled pressure regulation, timing control, and result logging—enabling concurrent validation of heterogeneous parts or batched identical units.
- High-stability mechanical pressure regulators supporting test ranges from 10 kPa to 500 kPa, calibrated to ±0.1% full scale accuracy with temperature-compensated silicon piezoresistive sensors.
- Configurable display resolution (0–4 decimal places) and dual-unit reporting for both test pressure (kPa, psi, bar, etc.) and calculated leak rate (SCCM, mL/min, Pa·m³/s), facilitating cross-functional data interpretation across global engineering teams.
- 64 total programmable test sequences—16 per channel—with user-defined ramp rates, stabilization periods, measurement intervals, and pass/fail logic (e.g., ΔP/t threshold, absolute pressure drop, or integrated leak accumulation).
- Rugged industrial enclosure (431 × 187 × 460 mm, ~14 kg), IP20-rated for cleanroom and production-floor deployment; compatible with standard compressed air or nitrogen supply lines (≥500 kPa, oil-free, dew point ≤ −40 °C).
- Compliance-ready architecture: audit trail logging, user-level access control, and timestamped result export (CSV/Excel) support GLP/GMP documentation requirements per FDA 21 CFR Part 11 when paired with validated software modules.
Sample Compatibility & Compliance
The ZH600-X accommodates a broad range of hermetically sealed devices—including medical implants (ISO 11607), automotive EV battery modules (UN 38.3 thermal cycling compliance), semiconductor packaging (JEDEC J-STD-020), and aerospace hydraulic fittings (ASME B31.4)—provided samples meet standard vacuum compatibility criteria (outgassing <1×10⁻⁶ Pa·L/s, non-reactive to He). Each channel accepts custom fixtures via ISO-KF25 or CF35 vacuum flanges. Regulatory alignment includes adherence to ISO 9001:2015 (process control), ISO/IEC 17025:2017 (testing laboratory competence), and EU Machinery Directive 2006/42/EC. Optional helium recovery integration reduces operational cost and environmental footprint in high-volume facilities.
Software & Data Management
Embedded firmware supports real-time waveform visualization, statistical process control (SPC) charting (X̄-R, Cpk), and automated report generation with embedded digital signatures. Data export complies with ASTM E2500-13 (verification of computerized systems) and enables seamless import into LIMS platforms (e.g., LabWare, Thermo Fisher SampleManager) via OPC UA or RESTful API. All test records include metadata: operator ID, calibration certificate ID, ambient temperature/humidity, and raw sensor timestamps—ensuring full traceability for internal audits or regulatory inspections.
Applications
- Automotive: EV battery pack housing integrity verification prior to electrolyte filling.
- Medical Devices: Sterile barrier system validation for Class II/III implants per ISO 11607-2 Annex D.
- Consumer Electronics: Waterproof rating confirmation (IP67/IP68) of smartphone enclosures and wearable housings.
- Aerospace: Hydraulic actuator manifold leak screening under MIL-STD-883 Method 1014.12.
- Energy Storage: Sealed supercapacitor and fuel cell stack envelope testing at elevated pressures (up to 500 kPa).
FAQ
What vacuum level is required for optimal helium mass spectrometer sensitivity?
The ZH600-X achieves best-in-class detection limits (≤5×10⁻¹¹ Pa·m³/s) when the analyzer’s ion source operates below 1×10⁻⁴ Pa—typically attained using integrated two-stage pumping (rotary vane + turbomolecular) with automatic pressure sequencing.
Can the ZH600-X be integrated into an automated production line?
Yes—digital I/O (24 V DC, opto-isolated) and Modbus TCP support PLC synchronization, robotic part handling triggers, and MES-level fault signaling without middleware.
Is helium consumption monitored and logged per test cycle?
Helium flow is metered via precision laminar flow elements; consumption data is recorded alongside leak results and exported with each test report.
Does the system support remote diagnostics and firmware updates?
Secure SSH and HTTPS interfaces enable authenticated remote access for troubleshooting and over-the-air updates compliant with IEC 62443-3-3 SL2 cybersecurity requirements.
How is calibration traceability maintained across multiple shifts?
Each calibration event generates a NIST-traceable certificate (with uncertainty budget), stored in immutable on-device memory and synchronized to central QA servers via TLS-encrypted transfer.
