摘要： The present invention provides an apparatus for use in measuring permeability of a material. The apparatus 1 comprises a non-conzact probs 6 comprising an inner pipe 8 and an outer pipe 10 which are arranged coaxially; a gas inlet for admitting a flow of gas into a first space 9 defined between the inner and outer pipes; and pressure difference measuring systems DP for measuring a pressure difference ΔP between said first space (PI) and a second space (P2) comprising the interior of the inner pipe8. The probe 6 is mounted on a moveable head assembly 11 and the apparatus 1 further includes a position control system 12, 22 for controlling the movement of the head assembly 11 so as to cause the probe 6 to scan across a surface 2 of the material to be analysed, while maintaining the probe 6 at a constant distance Z from said surface 2, and for collecting pressure difference ΔP measurements, using said pressure difference measuring device DP during scanning movement of the probe 6.
