“Mini-systems using an 8-liter rolling seal type spirometer. Each system contains a 10-inch color CRT, and both test results and respiratory waveforms are displayed on the CRT screen. Records are printed by a silent thermal printer. This model comes in three types. System-1 is the basic type and covers VC, FVC, F-V, MVV and MV tests. System-2 covers FRC test in addition to those of the basic type. System-3 covers FRC and DLco tests in addition to those of the basic type. Every type can be enhanced in system configuration after the initial purchase.”
