The D670 Mechanical Pressure-Regulated Touchscreen Differential Pressure Leak Tester is designed for accurate airtightness and leakage testing in industrial production. It uses a differential pressure measurement method and allows the test pressure to be adjusted manually through a mechanical control knob. This distinguishes it from the D670 electronic pressure-regulated model, which adjusts pressure through digital parameter input without a manual knob.
The instrument is equipped with a 5.6-inch touchscreen for test parameter configuration, operating-status monitoring, channel naming, and result review. Multiple optional test pressure and measurement ranges are available to accommodate different testing requirements.
The D670 provides 16 input and 16 output I/O control points for connection with PLCs, fixtures, solenoid valves, and other production-line equipment. These I/O points are used for external signal and equipment control and should not be interpreted as 16 independent leak-testing channels.
USB, Ethernet, RS232, and RS485 connectivity supports test data export and integration with compatible production equipment. The instrument can also connect to supported barcode scanners and printers, helping manufacturers improve product identification, test-record management, and production traceability.
Differential pressure resolution of 0.1 Pa/s: Delivers exceptional high accuracy to detect micro-leaks, ensuring strict quality compliance and reducing the risk of defective products reaching the market.
Multiple parameter channels (64 groups): Makes it incredibly easy to select, set, and switch parameters for different product lines without the need for constant reprogramming, saving valuable setup time.
16 digital inputs and 16 digital outputs for external equipment control: Provides extensive capability to connect with PLCs, fixtures, solenoid valves, and other external devices, thereby boosting overall testing efficiency.
Advanced channel management: Supports external start signals and parameter selection through compatible control interfaces effortlessly, with the added convenience that channel names can be manually input and named for intuitive identification on the factory floor.
Manual adjustment of output terminals: Fully supported to make external control integration significantly more flexible for customized production line requirements.
5.6-inch touchscreen display (resolution 640*480): Equipped with a highly intuitive Chinese operation interface, ensuring simple operation and a minimal learning curve for factory operators.
Three versatile startup modes: Choose from touch click, pre-set scanning, or remote control, accommodating various operational preferences and automation levels.
Flexible operational modes: Includes Manual testing mode, Automatic testing mode, and External control mode to suit both R&D laboratory environments and fast-paced automated production lines.
Massive data storage: Can save the latest 50,000 sets of detection data locally, allowing quality control managers to easily query test results by specific dates or channels for full traceability.
Automatic data retention: Leak detection result data is automatically stored with a reliable data memory function, preventing data loss during unexpected power interruptions.
Convenient data export: Can use USB, Ethernet, or RS485 export data functions; all exported data is formatted in EXCEL, making it highly convenient for editing, reporting, and analysis on a computer.
Product counting function: Effectively helps process and operation personnel quickly calculate the number of tested products, streamlining inventory and production tracking.
Three communication methods and interfaces: Includes network (Ethernet), RS232, and RS485, ensuring reliable integration with existing factory manufacturing execution systems (MES).
Rich remote control contacts: Can connect directly to a PLC or directly drive external mechanical devices (such as cylinders, etc.), eliminating the need for complex intermediary controllers.
Direct peripheral drive: Can directly drive a printer or scanner gun, specifically supporting designated models of scanner guns to scan QR codes and one-dimensional barcodes, which greatly accelerates product identification.
Sound and light alarm function: Instantly alerts operators to failed tests or system anomalies, ensuring immediate corrective actions and maintaining a safe working environment.
Bubble coating/pressure retention function: When using soap water to visually inspect for bubbles during manual verification, the instrument intelligently maintains the pressure retention state, facilitating accurate visual confirmation without pressure drops.
Low-voltage testing: Designed to operate on a DC24V safe voltage supply, which strictly adheres to industrial safety standards and protects both the operators and the device's sensitive electronic components.
