Summary:Consideration is given to the modernization of a pulse method of nondestructive control of the diffusion coefficient with the aim of improving the accuracy of its use to investigate massive products from porous materials. The method makes it unnecessary to precalibrate the used diffusant-concentration meter and ensures a rise in the accuracy of determining the sought diffusion coefficient due to the possibility to select measured parameters involved in a calculation expression on portions of the static characteristic of the sensor with high sensitivity and antijamming capability. Technical implementation of the method with a data-measuring system is considered.
