Gas flow calibrator OM SERIES

pressureleak

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. Leak rate: Available, 10-3 to 10-9 atm-cc/sec Temperature: Lowest temperature coefficient available, 0.2 %/°C ensures predictable leak rates over a wide temperature band Enclosure: Leaks supplied with 300cc or 500cc stainless steel cylinder (depending on leak rate) with DOT-3E1800 rating offering a maximum life span Certification: Supplied with N.I.S.T. certificate at no additional charge Features: Unique particle trap virtually eliminates clogging, typically associated with harsh environments. 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.
