 Performance features: 

The P670 is an electronic pressure-regulated direct pressure leak tester designed for industrial airtightness and leakage testing. Test pressure is set digitally through the touchscreen and controlled by the internal electronic pressure-regulating device, without using a mechanical adjustment knob. Multiple test pressure options and stored parameter profiles are available for different products and inspection requirements.

Precision Testing & Parameter Management

Ensuring accurate and repeatable test results is critical for maintaining product integrity. The P670 provides superior measurement precision and flexible channel configurations to accommodate diverse testing scenarios.

  • High-Accuracy Measurement: Features a high-resolution sensor capable of detecting pressure changes of <0.1kPa, ensuring highly accurate and reliable leak detection for sensitive components.

  • Extensive Parameter Channels: Supports up to 64 groups of Multiple Stored Test Profiles, allowing operators to easily select, configure, and switch between different testing parameters for various product lines.

  • Versatile Testing Modes: Equipped with manual testing, automatic testing, and remote control modes, providing operational flexibility based on specific production line requirements.

  • Pressure Retention & Bubble Inspection: Includes a dedicated bubble coating and pressure retention function. When using soap water for visual bubble inspection, the instrument steadily maintains the pressure retention state for accurate visual verification.

Advanced Automation & Integration

Designed for seamless integration into automated production environments, this instrument significantly reduces manual intervention and enhances overall testing throughput.

  • Robust I/O Capabilities: Features 16-channel output control and 16-channel control input, facilitating complex automated testing sequences and synchronized operations.

  • Flexible Startup Options: Offers three distinct startup modes: direct touch click on the screen, pre-set scanning initiation, or remote control activation.

  • Multiple Communication Protocols: Supports three communication methods and interfaces—Network (Ethernet), RS232, and RS485—ensuring broad compatibility with existing factory data networks.

  • Direct External Device Drive: Equipped with rich remote control contacts that can directly connect to PLCs or independently drive external automated devices, such as pneumatic cylinders, without the need for additional relays.

  • Customizable Remote Operations: Allows remote control to start tests and switch channels. Channel names can be manually inputted and customized for clear identification during remote operation.

  • Adjustable Output Terminals: Manual adjustment of output terminals is supported, making external control configurations more flexible and adaptable to specific fixture setups.

Comprehensive Data Management & Traceability

Effective quality control requires meticulous data tracking. The P670 offers extensive data storage and export capabilities to support rigorous quality assurance and traceability protocols.

  • Massive Data Storage: Capable of saving the latest 50,000 sets of detection data locally. Operators can easily query historical test results by specific dates or channels for auditing purposes.

  • Automatic Data Memory: Leak detection result data is automatically stored with a secure data memory function, preventing data loss during unexpected power interruptions.

  • Convenient Data Export: Test records can be exported via USB, Ethernet, or RS485. The exported data is formatted in EXCEL, making it highly convenient for further editing, analysis, and reporting on a computer.

  • Peripheral Device Support: Can directly drive external printers or scanner guns. It supports specific models of scanner guns for scanning QR codes and one-dimensional barcodes, streamlining product identification and tracking.

  • Integrated Product Counting: Features an automatic product counting function that helps process engineers and operational personnel quickly calculate the total number of tested products and monitor production yields.

User-Friendly Design & Operational Safety

Prioritizing operator safety and ease of use, the instrument is designed to minimize training time and ensure a secure working environment during high-pressure testing procedures.

  • Intuitive Touchscreen Interface: Features a clear 5.6-inch (640*480 resolution) touchscreen display with an intuitive operation interface, enabling simple operation and quick parameter adjustments.

  • Safe Low-Voltage Testing: Operates on a DC24V safe voltage for low-voltage testing components, significantly reducing electrical hazards for operators on the factory floor.

  • Sound and Light Alarms: Equipped with a highly visible and audible sound and light alarm function to immediately alert personnel of any testing anomalies, leaks, or system faults.

Instruction Manuals

The P670 Electronic Direct Pressure Leak Tester is engineered for straightforward integration into complex industrial testing environments. To accommodate various facility requirements, the system supports multiple operational methodologies, including manual intervention, fully automated testing sequences, and remote control operations. Operators can efficiently manage testing cycles through intuitive touch interfaces, utilize barcode scanning for rapid parameter configuration, or deploy remote management systems for centralized oversight.
