    For research and development of products requiring flow metering, it is convenient to have an accurate array of precision orifices. The kits described on this page provide a wide range of orifice sizes and a corresponding wide range of metered flow. Metal orifice and sapphire orifice kits use compartmented plastic boxes for storage of the precision restrictors. The Micro-Orifices® provided in kits include protective screens to protect against contamination during handling and installation.
