  The beam intensity supplied by HIRF-CSR has a wide range, high-intensity primary beams and low intensity fragment-beams in connection with the slow extraction and the fast beam-extraction from the synchrotron CSRm. The detector (CG) has been developed for the beam profile monitoring at radioactive beam line HIRFL-CSR. The front-end electronics are based on CPLD controlled sample-and-hold circuits and multiplexer. Remote control is used to tune the detector sensitivity by setting the gas pressure in the detector's cell, the bias voltage of the anode and the integration time. The test measurements results are presented in this paper. Keywords: beam profile monitor; current grids; multiplexer; HIRFL CSR;
