Multiple Gas Type Orifice Leak Testing Calibrators
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.

Lowest temperature coefficient available, 0.2 %/°C ensures predictable leak rates over a wide temperature band
|Ordering Information for OM Series||
Available in a wide range of gases as coded below. Specify gas code and leak rate.
When ordering Part No. 922-XYY, X = Leak Rate Exponent and YY = Gas Code from the chart below. Leak Rates: 10-3 to 10-9.
Example: OM No. 922-501 = 10-5 range Helium Leak
All leaks filled with high purity gases. All OM models supplied with 1/2″ OD smooth tube connection unless otherwise specified. OM-3 range leaks provided with 500 cc volume.
Please note that other gases and specific leak rate values are also available upon request. Available gases include:
02 Helium 3
13 Carbon Dioxide
14 Carbon Monoxide
17 Sulfur Dioxide
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.
