OM Series Calibrated Gas Leaks
OM
The OM Series gas calibrator leaks utilize a precision tapered glass capillary as the leak element. Gases pass through a single orifice, with the leak rate dependent upon size and gas pressure. To prevent clogging of the fine orifice, a unique particle trap is located between the capillary tube and outlet fitting. Available in a wide variety of gases (see ordering information.)

Other gases and specific leak rate values are available upon request. At an additional charge, all OM model gas leaks can be supplied at a specific leak rate ±1 of specified leak rate (example: a 2.5 x 10-5 atm-cc/sec specified will receive leak at 1.5 to 3.5 x 10-5 atm-cc/sec) or, at an extra close tolerance of specific leak rate ±0.5 of specified leak rate (example: a 2.5 x 10-5 atm-cc/sec will receive leak at 2 to 3 x 10-5 atm-cc/sec.
