Metal Seal Gas Mass Flow Meters and Controllers of Bronkhorst are characterised by their unique, patented metal-to-metal seal construction with excellent resealing capability. Furthermore they distinguish themselves by a high surface quality and are therefore especially suitable for meeting the semiconductor and solar industry requirements as well as other high purity gas applications. The base blocks of the Mass Flow Meters and Controllers have 1/4" face seal male (VCR) connections.
