Master these helium mass spectrometer leak detector tips to easily spot vacuum coating equipment leaks!

The correct use of helium mass spectrometer leak detector is very important for detecting the leakage of coating machine equipment and routine maintenance. Vacuum coating equipment has the problem of poor air tightness, if you carry out an air tightness test after maintenance, you can avoid the production of many unqualified products, thereby saving costs.

About the use of helium mass spectrometer leak detector vacuum coating machine, the following are some common questions and answers:

Helium mass spectrometry leak detector adopts vacuum method for leak detection. Set the leakage rate value in vacuum mode, connect the helium mass spectrum leak detector to the bypass of the coating machine through the bellows, and then spray helium in the suspected leakage places (such as pipelines, joints, etc.) to complete the leak detection.

What is helium injection?

Helium injection method is a commonly used helium mass spectrometry method for leak detection in vacuum coating. It uses the high diffusivity and low solubility of helium to detect whether there is a gas leak by injecting helium into the component or system to be tested.
