IUT - Permeation Based Calibrator - Datasheet

The principle of the Perm-Calibrator is permeation. Permeation (lat.: permeare = percolate, penetrate) describes the process of penetration of a substance through a solid material, driven by the force of a chemical potential gradient like a pressure or a concentration difference. Without any external influence the substance which permeates, moves always into the direction of the lower concentration.
