A laboratory setup for the study of wide-range piezo-sorption sensitive elements in
the measurement of gas humidity using nitrogen as an example was assembled. It is determined that
all sensitive elements have a variation of statistical parameters, which leads to an error. To reduce the
error, it was pro-posed to introduce a correction factor. To determine the nominal static characteristics, the results of the experiments were approximated by a polynomial of the 6th degree. In connection with the difficulty of identifying the model parameters, it was proposed to use 3rd degree polynomials in various parts of the humidity concentration.
