      Five Reasons To Choose Radiflo®

The Radiflo® non-destructive leak detection system is of vital importance to you, as manufacturer or user of hermetically sealed components. Listed below are five reasons which prove Radiflo® to be the finest, yet least expensive leak detection system available.

Radflo 1It provides a test for component leakage after all sealing operations are complete. This is most important to receiving as well as production test departments.
Isovac 2Components which fail when extremely small leaks occur, can now be tested to 10-12 cc/sec by development or production departments. You can be assured that your components will function after long shelf life.
Krypton 85 3Radiflo® tests non-destructively. Sensitive components in sealed containers can be graded and used in applications according to their seal requirements. Transistors which can't be used in missiles, can be used in products with less critical specifications, not thrown away.
leak testing 4Radiflo® can process thousands of components daily with immense savings in production and testing cost without bottlenecking production. Example: transistors tested for less than one cent each, included material, labor and burden.
IsoVac 5Radiflo® can be automated thereby controlling to a great extent the often inevitable slip-ups due to the human mechanism (human error).
