Different measurement methods of helium mass spectrometer leak detector meet various needs

The key components of the helium mass spectrometry leak detection system in the helium mass spectrometry leak detector are all imported, ensuring stable and reliable performance. With its slender volume and superior performance, it is suitable for numerous industries. By applying the principles of helium mass spectrometry and inverse diffusion, and adopting an original imported molecular pump, a 180° non-uniform magnetic field, and fully automatic control technology, it achieves automatic helium peak scanning, automatic zero adjustment, automatic calibration, and automatic range switching. It features fast detection speed, high detection sensitivity, and strong anti-interference ability. The helium mass spectrometry leak detector can conduct fine leak detection on the airtightness of microelectronic or semiconductor device packages with an internal cavity. Helium is selected as the tracer gas for this detection method. Helium has the advantages of a small mass number, light weight, and strong penetration ability, thus achieving the purpose of fine leak detection.

Features of the helium mass spectrometry leak detector:

1. The detection time and response cycle are extremely short, which can be within 2 seconds.

2. The detection medium is quite common, and only compressed air is required.

3. There are multiple large leak protection modes, which fully protect the ion source from oxidation and prevent the molecular pump from being impacted when exposed to the atmosphere.

4. Large leak detection function: By presetting the pressure, when evacuating, if the preset value cannot be reached, the leak detector will automatically give an alarm prompt.

5. Multiple measurement units can be selected, the detection data is updated in real time, and an Excel form can be directly generated and output.
