Portable desktop spirometer

A desktop spirometer developed for occupational health professionals and breathing experts who regularly conduct lung function tests to identify respiratory issues.

Featuring a gold standard digital volume transducer recognised internationally for accuracy and being able to measure at very low flow rates, healthcare professionals can be confident that test results are reliable and precise when considering a lung function diagnosis.

This spirometer is lightweight and portable, including a carry case, making it easy to transport between clinics and workplaces. 

Please note: The ML3500-Mk8 is manufactured by CareFusion and is distributed by Amplivox Ltd.

Supportive design

With a high-resolution colour touch screen and an icon-based menu and stylus, the ML3500-Mk8 is an intuitive spirometer enabling Vital Capacity (VC) and Forced Vital Capacity (FVC) spirometry tests to be performed with ease. The spirometer offers real time viewing when lung function tests are being performed, and the combined on-screen prompts for slow start, low volume, and short blow during the spirometry test ensures a high level of quality control.


Key features

  • Compliant to ERS 2005 standard
  • High-definition, icon-based, colour display
  • On screen predicted value and results interpretation
  • Numerous predicted values and languages
  • Test quality assurance prompts
  • Integrated high-resolution printer with paper load mechanism
  • 2000 patient test memory capability
  • PC interface and optional software

Testing abilities

The ML3500-Mk8 features 41 parameters with actual, predicted, and percent predicted values, as well as normal range, with the option of interpretation and equivalent lung age reporting. A full internal database allows complete patient recall on both data and measured loops. All of the chosen parameter results are displayed with an option to
review the volume/time curves and the flow/volume curves, so the user can obtain accurate results for further investigation.

Test results may be shown on the colour screen, saved in memory, printed on an internal printer, and/or exported to the optional spirometry PC database for complete flexibility.



The ML3500-Mk8 allows for a variety of mouthpieces to be used in conjunction with an occupational screening programme ensuring safe and hygienic testing. Disposable turbines with mouthpieces are an optional extra for eliminating cross contamination and providing a sanitary and accurate solution. Bacterial viral filter (BVF) mouthpieces provide a safe way to complete spirometry whilst providing reassurance to the patient.
