Vacuum systems come in a wide variety of structures with different leak detection approaches. Many manufacturers have developed special equipment for tightness testing: vacuum leak detectors. Yangning (Xiamen) Intelligent Technology Co., Ltd. will explain key factors to consider when purchasing vacuum leak detectors.
I. General Conditions for Leak Detection Methods
1. Excellent leak detection sensitivity to capture tiny leak holes; 2. Quick response to boost overall testing efficiency; 3. Support leak positioning and quantitative measurement. It can locate leak holes and measure leak rates to verify whether products meet quality specifications; 4. Adopt non-destructive testing, preventing damage or contamination to tested devices; 5. Stable long-term performance, maintaining consistent detection sensitivity during continuous operation; 6. The tracer gas used exists in low concentration in air. It is non-toxic and will not corrode mechanical components; 7. Broad detectable range covering large leaks and micro leaks, lowering the quantity and procurement cost of testing equipment; 8. Oil-free and clean testing procedure to meet the requirements of special working environments. ### II. Basic Principles for Selecting Vacuum Leak Detection Solutions 1. The allowable leak rate of tested equipment serves as the core selection reference. The allowable leak rate is the total leakage of all holes. To pinpoint a single leak, the sensitivity of the selected solution should be 1~2 orders of magnitude higher. For instance, if the allowable leak rate of equipment is 10⁻¹¹W, a detector with sensitivity ranging from 10⁻¹² to 10⁻¹³W is recommended; 2. Select user-friendly and cost-effective solutions based on the actual working conditions of tested workpieces. The Helium Mass Spectrometer Leak Detector manufactured by Yangning (Xiamen) Intelligent Technology Co., Ltd. delivers accurate measurement, rapid response and reliable safety. It suits diverse scenarios. The compact unit is easy to transport and performs well in both leak pinpointing and leakage measurement.
