Technology
Reliably identifies overall leakage
Fast leakage measurements
No man-made errors
Process is easy to automate
Helium needs no purification to remove contaminants
Equipment is large-scale [We offer separate, simplified models(detection performance subject to certain conditions)]
Cannot identify separate individual leak positions
Directly finds the leak points
Installation is simple (needs little space)
Inexpensive equipment costs
Cannot measure leak unless probe directly contacts the leakage point
Operating the probe requires considerable experience
Cannot measure leakage quantity for entire work piece
