PM Series Calibrated Gas Leaks

PM

The PM Series – Helium based – Gas Permeation Leak Calibrators utilize a durable 7740 Pyrex glass permeation leak element which permits diffusion of helium gas. Helium diffuses through the glass membrane at a constant rate determined by the membrane thickness and surface area. These leaks are highly resistant to clogging by nature of their design.
