Shanghai Bodong Germany Pfeiffer Portable Helium Mass Spectrometer Leak Detector ASM 310 was successfully applied to leak detection by a scientific research instrument of a Chinese Academy of Sciences. The teacher used Pfeiffer products 10 years ago. With the recognition of the Pfeiffer brand, product quality and stability, Shanghai Bodong successfully recommended the Pfeiffer Portable Helium Mass Spectrometer Leak Detector ASM 310 based on the teacher's equipment.
Reasons for leak detection: Many cutting-edge scientific research projects need to be conducted in specific environments such as vacuum, microgravity, and high and low temperatures. This is why some materials have to carry spacecraft into space for experiments because space provides vacuum and microgravity conditions. However, not all topics have the opportunity to enter space research, then how to obtain vacuum on the ground? This requires the use of vacuum pumps. However, sometimes the vacuum leaked due to the leakage of the cavity could not be pumped down, and the conventional leak detection method was difficult to find the missing point, which was time-consuming and laborious and failed to achieve results. At this time, helium mass spectrometer leak detectors are needed for leakage detection. Shanghai Bodong Pfeiffer vacuum pump and helium mass spectrometer leak detector have been widely used in research institutes and universities' key laboratories.
Leak detection method: helium mass spectrometer leak detector ASM 310, the use of vacuum leak detection, specific practices are as follows:
1. Connect the scientific research equipment to the leak detector ASM 310 through a corrugated hose and check whether the clamps at both ends are buckled.
2. Start the ASM 310 and enter the standby interface; the initial start-up time is approximately 3 minutes, and the start-up time is < 1 minute.
3. Press the start button, the leak detector will automatically vacuum, and at the same time, the device will blow helium gas where there is leakage; if there is any leakage, the leak detector will alarm immediately, indicating that there is leakage at the injection point.
4. After the test is completed, press the leak detector standby button, vent the air, turn off the power, and remove the connecting line.
