This paper describes a computer program that implements an algorithm for com- pressing technological information with losses using archive data of the information-measuring system "Skala-micro" of the Kursk and Smolensk NPPs as an example. The presented al- gorithm allows to compress file archives at the data level with the possibility of their quick subsequent recovery within the limits of the acceptable error. The main goal of the algorithm is to significantly reduce the excess amount of memory when storing data for its subsequent more efficient use.
