Alpha Touch Spirometer

Performing spirometry tests could not be easier than with the new Micro Direct alpha touch spirometer. Simply enter the patient’s details on the color touch-screen display, select FVC or VC and begin the test series.



Test information is presented in an easy to read format on a clear, bright color display. The best test is automatically selected and built-in quality control checks insure accurate results. Test data along with the diagnostic interpretation and estimated lung age can be instantly printed on the integrated printer, converted to a PDF and printed using the included reports PC software or downloaded to the optional Spirotrac PC Software.



The alpha touch features a highly accurate Fleisch pneumotach flow measuring system, battery operated portability and is shipped complete with all necessary accessories in a study carrying case. The easy to use and affordable all-in-one alpha touch spirometer provides a fast, accurate and cost effective spirometry solution.
