Overview
The SUNS SHH100 Positive/Negative Hybrid Pneumatic Leak Tester is an engineered solution for quantitative, high-reproducibility leak detection and pressure decay analysis across regulated manufacturing environments. It operates on the principle of differential pressure decay measurement—applying controlled positive or negative test pressure to a sealed component or assembly, then monitoring minute pressure changes over time to quantify leakage rate. The system integrates a precision pneumatic architecture with dual-mode capability: it supports both pressurization (positive-pressure testing) and evacuation (negative-pressure/vacuum testing) within a single platform, enabling comprehensive validation of sealing integrity for diverse part geometries and material systems—including plastic housings, medical device enclosures, automotive fluid reservoirs, and consumer electronics casings. Its core measurement engine features a 32-bit embedded processor paired with a 24-bit analog-to-digital converter and proprietary AI-accelerated signal processing firmware, ensuring rapid stabilization and low-noise data acquisition even under dynamic environmental conditions.
Key Features
- Dual-mode operation: seamless switching between positive-pressure (5–800 kPa) and negative-pressure (5–85 kPa) test protocols without hardware reconfiguration
- High-fidelity sensing architecture: factory-calibrated imported pressure transducer chip with automatic thermal drift compensation and real-time environmental offset correction
- Precision pneumatic control: SMC-sourced high-stability pressure regulator and ultra-sensitive feedback sensors ensure repeatable pressure ramping, hold, and decay profiling
- Industrial-grade human-machine interface: 10-inch capacitive LCD touchscreen with intuitive, OS-native navigation—designed for glove-compatible operation in cleanroom and production-floor settings
- Robust connectivity suite: dual communication options (RS-232/RS-485 serial + Ethernet via RJ45) support integration into factory-wide SCADA, MES, and PLC networks
- Scalable architecture: base unit supports single-channel operation; modular expansion enables up to 8 independent test channels via synchronized master-slave configuration
Sample Compatibility & Compliance
The SHH100 accommodates a broad range of test specimens—from small-diameter tubing connectors and syringe barrels to large-volume battery enclosures and HVAC components—via customizable fixturing and adaptable port interfaces. All pressure test sequences adhere to fundamental principles outlined in ISO 50001 (energy-efficient pneumatic testing), ISO 15500-4 (pneumatic component testing), and ASTM E499-22 (standard practice for leak testing using pressure change methods). When deployed in pharmaceutical or medical device manufacturing, the system supports audit-ready operation: timestamped test logs include operator ID, part barcode, environmental metadata (temperature/humidity), and full traceability of pass/fail criteria per U.S. FDA 21 CFR Part 11 requirements—provided external authentication and electronic signature modules are implemented per site-specific validation protocols.
Software & Data Management
The embedded operating system provides native support for barcode scanning (via integrated USB or optional Bluetooth scanner), automatic population of lot/batch identifiers, and structured export of test records in CSV and XML formats. All measurement data—including raw pressure vs. time curves, calculated leak rates (Pa/s or cc/min equivalents), and statistical summaries (mean, SD, Cp/Cpk)—are stored locally with configurable retention policies. Network-enabled units synchronize historical datasets to centralized SQL databases or cloud-based LIMS platforms. Audit trails record every parameter change, user login/logout event, and calibration action with immutable timestamps—fully compliant with GLP and GMP documentation standards when validated per IQ/OQ/PQ protocols.
Applications
- Automotive: valve body assemblies, brake fluid reservoirs, EV battery module seals, and HVAC evaporator cores
- Medical devices: infusion pump housings, inhaler canisters, surgical instrument sterilization trays, and implantable device packaging
- Consumer electronics: waterproof smartphone and wearable enclosures, smart speaker acoustic chambers, and drone propulsion housings
- Industrial components: solenoid valve bodies, pneumatic cylinder end caps, and compressed air filter housings
- Quality assurance labs: incoming material verification, in-process sampling, and final product release testing under ISO 9001-certified workflows
FAQ
What pressure ranges does the SHH100 support for positive and negative testing?
The SHH100 offers two calibrated pressure domains: 5–800 kPa for positive-pressure applications and 5–85 kPa for vacuum/negative-pressure testing—both referenced to ambient atmospheric pressure.
Can the SHH100 be integrated into an existing MES or ERP system?
Yes—via RS-232/RS-485 serial or Ethernet (RJ45), the instrument supports Modbus RTU/TCP and custom ASCII command protocols for bidirectional data exchange, including real-time pass/fail status, test parameters, and full trace logs.
Is multi-channel expansion supported out-of-the-box?
The SHH100 is supplied as a single-channel unit, but its firmware and I/O architecture are designed for seamless multi-channel deployment using optional synchronization modules and external manifold manifolds—up to eight parallel test stations per master controller.
Does the system meet regulatory requirements for use in FDA-regulated environments?
When installed, configured, and validated per site-specific protocols—including user access controls, electronic signatures, and audit trail activation—the SHH100 meets foundational data integrity expectations aligned with 21 CFR Part 11, Annex 11, and ISO 13485 quality management system clauses.
What maintenance intervals are recommended for long-term accuracy?
Annual calibration against NIST-traceable pressure standards is recommended; sensor zero-point auto-compensation occurs continuously during idle periods, minimizing drift-related recalibration frequency.
