Automated Humid Air Porometer
Description:
ā
Advanced Automated Porometers yield very objective, accurate and reproducible results, considerably reduce test duration, and require minimal operator involvement. The machine is fully automated and designed for linear turbulance-free test gas flow. The pressure is measured close to the sample and therefore, the correction term in the differential pressure measurement is minimized. Required amount of pressure is uniformly applied to the o-ring seals on the sample and the need for hand-tightening of the cap on the sample chamber is eliminated. Automatic addition of wetting liquid reduces test time appreciably. This sophisticated instrument has found applications in a wide variety of industries.
