“A new model containing an 8-inch color CRT. Both test results and waveforms are displayed on the CRT screen. If measurement is made two times to obtain the best result, the respective respiratory waveforms can be displayed simultaneously in different colors for convenience of selection. The respiratory waveforms obtained before and after medication can be compared on one screen, and the rates of change in test results can be displayed. Records are printed by a silent thermal printer. The analyzer can be modified to be connected with a general purpose computer, for transfer of data.”
