Why not : continuous dilution with capillaries

We know MFCs diluters are flexible but unaccurate and unstable and capillaries type gas dividers are stable and accurate but rigid. Why not to make a gas diluter flexible, accurate and stable ?  BetaCAP30x100 is the answer.  It's a gas divider made by two capillary modules : a fixed pre.divider 1:100 and a 30 steps divider 0...100%.  The final result is a 30 + 30 steps gas divider, operating both in the renge of emissions (30 steps from 0 to 100%) and air quality (30 steps from 0,033% to 1%).  The newest performance of this gas diluter is to allow overcoming the "step by step" division : using automatically in a clever mode the very accurate pressure electonic regulation, a continuous selection of the diluted gas concentration is allowed in the range 0,025%...98,5%.
