The P650 Electronic Touchscreen Leak Tester applies the direct pressure decay method to verify sealing integrity on electronics assembly lines. Unlike the mechanical variant, this model sets test pressure through digital input on the touchscreen rather than a physical knob. Pressure values are entered numerically and stored in parameter channels, ensuring consistent repeatability across batch runs where the same test recipe is used thousands of times. The instrument supports selectable test pressures from 50 kPa to 1600 kPa, addressing mid-to-high pressure sealing checks on electronic enclosures, sensor packages, and connector assemblies. It runs on DC24V and uses clean compressed air or nitrogen compliant with ISO 8573-1 or JIS B8392-1 as test media.
The electronic P650 model adjusts test pressure through numeric input on the 5.6-inch resistive touchscreen. Operators enter the target pressure value directly, and the internal regulator maintains the setpoint automatically. There is no manual knob on this model, which reduces the risk of accidental pressure changes during unattended operation and makes the instrument suitable for fixed-recipe production lines where test parameters are locked by supervisory personnel.
The instrument measures pressure decay at 0.001 kPa display resolution and 0.1 kPa measurement resolution, converting the decay into leakage rate units such as ml/min or Pa·m³/s. It supports leakage, reduction, blockage, and fatigue measurement patterns. A built-in temperature compensation module and automatic zero-point offset correction minimize measurement drift caused by the temperature fluctuations common in electronics assembly environments where climate control varies between shifts.
The 5.6-inch color LCD display (640×480 resolution) hosts 64 parameter channels, each retaining independent pressure, timing, and pass/fail threshold settings for different product models. Channel names accept manual input in both Chinese and English. Three start methods are available: touchscreen tap, pre-set QR code scanning, and external signal trigger via the wired I/O terminal. The instrument does not offer wireless remote control; external activation is exclusively through wired I/O or network commands.
Internal storage retains 50,000 test records, searchable by date or channel, with Excel-format export through USB, Ethernet, or RS485. Communication interfaces include Ethernet, RS232, and RS485. Sixteen input and sixteen output I/O channels support PLC integration and direct control of external clamping cylinders. The instrument is compatible with label printers and designated QR code/barcode scanners. A buzzer and on-screen indicator provide failure alerts, and a pressure-hold mode enables soap-bubble visual leak localization by sustaining pressure after the automated cycle completes.
The P650 electronic model is deployed on electronics assembly lines where test recipes are standardized and repeated at high volume. Common test objects include sealed sensor housings, PCB enclosure gaskets, camera module seals, connector watertightness checks, and battery pack enclosure verification. The digital pressure input method ensures that each unit is tested at the identical setpoint, reducing operator-induced variation on lines running the same product for extended periods. The 16 I/O channels and Ethernet/RS485 connectivity allow the instrument to slot into automated assembly cells managed by PLC or MES systems. Excel data export supports batch-level quality records required by electronics manufacturing audit processes.
Test pressure is entered numerically on the 5.6-inch touchscreen and stored in the selected parameter channel. There is no physical regulation knob on this model. The internal electronic regulator maintains the entered setpoint automatically during each test cycle.
Selectable test pressures are 50, 100, 200, 500, 700, 1000, and 1600 kPa. The electronic model does not offer the 20 kPa low-pressure range that is available on the mechanical P650 variant. Negative pressure ranges are also available as selectable options depending on the ordered configuration.
No. The P650 electronic model does not include wireless remote control functionality. External start and channel switching are handled through wired I/O terminals (16 input channels), Ethernet commands, or RS485 communication, making it compatible with standard PLC-controlled production lines.
The instrument stores 64 parameter channels, each holding independent pressure, timing, and threshold settings. Up to 50,000 test result records are retained internally and can be queried by date or channel number. Records are exported in Excel format via USB, Ethernet, or RS485 for quality analysis and traceability reporting.
