Company Overview

Helium Mass Spectrometry Air Tightness Detection System

Compared to differential pressure and water immersion methods used up to now, the helium test method is highly reliable and highly accurate inspections can be made in a short time.

What attributes do you look for when recruiting graduates?

Therefore, this method is ideal for mass-production needs at the work site.
Main technical performance:
1.Vacuum box size according to the size of the product to determine
2.generally two boxes of linkage system,beat up to 40~60S/box
3.open the door way:according to process requirements design,generally drawer,pull type
4.The vacuum box sets the safety grating
5.With clear helium function
6.helium can be recovered,the recovery rate of up to 98%.

What key advice would you give to China students/graduates who would like to work for your company?
