Lungtest 1000 spirometer designed for pulmonological tests is a stationary modular device able to perform computer analysis of the measurements, operated by any PC with software implemented in any version of Microsoft Windows system. This concept allows practically unlimited implementation of new elements into the test system. Lungtetst 1000 spirometer is made in three basic versions: Lungtest 1000 with unlimited development options Lungest 1000 S and Lungtest 1000 SB with limited development options. All versions of Lungest 1000 are operated with a program compliant with ERS/ATS standards controlling the tests according to ERS/ATS recommendations. A message confirming meeting of ERS/ATS recommendations is printed only on reports of properly performed tests.
