SL Standard Leak
In air tightness testing, how can you be sure that the testing equipment itself is accurate and reliable? The AMT Standard Leak is designed exactly for this purpose – it is a precision component that produces a constant, known leak rate at a specified pressure, serving as a “measuring ruler” for leak detection systems. It is used to verify instrument accuracy and calibrate test systems, making it an indispensable core accessory for metrology departments and leak testing equipment maintenance. The SL Standard Leak is a reference standard in the field of leak detection. It incorporates a micron‑scale channel or permeation element that outputs a highly stable and reproducible leakage flow at a given pressure. By connecting the standard leak in parallel to a leak testing system, you can quickly and economically verify the proper function of the entire test loop – including the instrument, tubing, and fixture.
Main parameters
Selection & Customization
Flow rate: Any value from 0.1 to 200 ml/min (requires specifying target pressure and leak rate)
Pressure: -95 kPa to 1500 kPa (vacuum or positive pressure)
Connection: Standard 1/8″ or 1/4″ quick‑connect fittings; optional threaded, ferrule, or custom interfaces
Additional features: Optional shut‑off valve, dust cap, or identification label
Technical Advantage
Key Advantages
Precise & quantitative: Custom‑produced leak rate (e.g., 5 ml/min @ 100 kPa) according to the user‑specified test pressure, meeting different process standards.
Long‑term stability: Manufactured from pressure‑resistant, corrosion‑resistant materials with precision machining; minimal change in leak rate, reusable tens of thousands of times.
Plug & play: Directly connect to the calibration port of an air tightness tester or in series/parallel with the test circuit – no complex modification required.
Wide range coverage: Flow range 0.1 ml/min to 200 ml/min; pressure range -95 kPa to 1500 kPa (including vacuum and positive pressure), covering common leak detection scenarios.
Traceable certificate: Supplied with a calibration certificate traceable to NIST (National Institute of Standards and Technology), meeting the measurement traceability requirements of quality systems such as ISO 9000 and IATF 16949.
Industrial design: Designed for frequent use in factory environments – rugged, durable, and resistant to contamination.
Flexible connections: Various mechanical connection types available (quick‑connect, threaded, ferrule, etc.) – can be customized per customer requirements.
Typical Applications
| Use Case | Procedure | Purpose |
|---|---|---|
| Daily verification | After shift changes, fixture changes, or repairs, connect the standard leak into the test loop. | Quickly confirm that the leak tester and system are functioning properly. |
| Accuracy calibration | Connect to the calibration port of the leak detector; compare the instrument reading to the nominal value of the standard leak. | Correct instrument deviation and ensure measurement accuracy. |
| Measurement comparison | Use the same standard leak for comparative testing between laboratories or within a company. | Unify leak measurement values and eliminate systematic errors. |
| Equipment acceptance | After receiving new leak testing equipment, use the standard leak to verify performance. | Confirm that the equipment meets technical specifications. |
Measure precision with the standard as your ruler.
