The F650 is a flow-type air tightness leak detector designed for production-line quality control in automotive manufacturing and related industries. Operating on a flow-based measurement principle, the instrument quantifies leakage by measuring the volumetric flow rate required to maintain a stable test pressure inside a sealed component. This approach provides direct leakage readings without requiring volume conversion, making it suitable for high-throughput testing environments where rapid pass or fail determination is essential.
The detector supports a broad selection of test pressure ranges, spanning negative pressure configurations from -98 kPa to -2 kPa and positive pressure configurations from 5 kPa to 1000 kPa, allowing industrial clients to select the range that matches their specific test requirements. Ten flow measurement ranges are available, from 5 mL/min to 100 L/min, covering both micro-leakage and large-leakage detection scenarios.
The F650 employs mechanical pressure regulation via a physical rotary knob located on the front panel. Operators adjust the test pressure manually by turning the knob, with the current pressure value displayed on the touchscreen. This mechanical design provides direct tactile feedback and does not rely on digital input interfaces for pressure setting, making it straightforward to operate on the factory floor.
A 5.6-inch color LCD resistive touchscreen with a resolution of 640×480 pixels serves as the primary operator interface. The system stores up to 64 parameter channels, each holding a complete set of test configurations including pressure, timing, thresholds, and channel name. Operators can switch between channels manually or via external relay, network, or RS485 signals, enabling multi-product testing on a single instrument without reconfiguration. Channel names support both Chinese and English character input.
The F650 provides 16 input channels and 16 output channels for external system integration. These I/O terminals allow the detector to interface with PLCs, conveyor systems, and automated test fixtures. External signals can trigger test starts and channel switches, while output relays can directly drive external actuators such as clamping cylinders. The instrument does not include wireless triggering capability; all external activation is performed through wired I/O connections.
Test results are automatically stored in internal memory with capacity for up to 50,000 data entries. Records can be queried by date or channel number and exported via USB, Ethernet, or RS485 interfaces in Excel-compatible format for further analysis. Three communication protocols are supported: Ethernet, RS232, and RS485. The detector also supports optional label printers and specific QR code and barcode scanner models for traceability integration.
The F650 is deployed across automotive component manufacturing, including engine parts, fuel systems, brake lines, cooling systems, and battery housings for electric vehicles. Beyond automotive, commercial users in electronics manufacturing, medical device assembly, and aerospace component production utilize the instrument for sealed-component quality verification. The built-in temperature compensation module corrects for thermal drift during testing, while the pressure-hold function allows operators to perform soap-water visual bubble inspection alongside automated measurement.
The F650 offers selectable pressure ranges including negative pressure options (-50 to -2 kPa and -98 to -2 kPa) and positive pressure options from 5 kPa up to 1000 kPa. Business buyers should specify the required test pressure when ordering.
This model uses mechanical pressure regulation. A rotary knob on the front panel allows manual pressure adjustment, with the set value displayed on the touchscreen. No digital pressure input interface is provided on this mechanical configuration.
No. The F650 does not include wireless remote triggering. External test start and channel switching are achieved through wired I/O terminals (16 inputs, 16 outputs) that connect to PLCs or automation systems.
The F650 operates with clean compressed air or nitrogen meeting ISO 8573-1 or JIS B8392-1 quality standards. The test air source should exceed the desired test pressure by at least 0.05 MPa.
Internal memory holds up to 50,000 test records, which can be queried by date or channel and exported via USB, Ethernet, or RS485 in Excel-compatible format.
