The LDS3000 AQ is a leak detector for accumulation testing. It runs on low-cost forming gas or helium as the tracer gas and closes the gap between air testing (pressure drop testing) and helium vacuum testing. Test results are not affected by temperature or moisture, which makes it well suited to finding liquid leaks such as oil or water leaks.
| Detection Method | Accumulation method: the part under test is filled with tracer gas and placed in an accumulation chamber, and the leak rate is determined from the quantity of tracer gas accumulated in the chamber |
| Tracer Gas | Forming gas (95% nitrogen, 5% hydrogen) or helium |
| Measurement Range | 5 decades |
| Test Chamber Pressure | Atmosphere (standard pressure) |
| Response Time | Less than 1 s |
| Detection System | 180° sector field mass spectrometer |
