MicroLoop spirometer

Conduct portable spirometry

Our highly portable MicroLoop spirometer can be used in physician offices or for bedside testing of FVC and SVC.

Color-guided usability

A high-definition color touchscreen enables easy access to functions.

Full configuration

The system lets you select up to 41 indexes, including predicted values and languages.

On-screen convenience

Using full flow volume and volume time curves, you can inspect maneuvers while following test-quality screen prompts.

Convenient animation

With three computer animation incentive programs, the spirometer helps you improve repeatability and performance. 

Data sharing

The spirometer can download spirometry data into Vmax® Encore software and SentrySuite® software.

Direct printing option

A USB connection on the spirometer gives the option of directly printing on external printers.

Standards compliance

The system completely complies with ATS/ERS 2005 standards.

Convenient packaging

The spirometer comes in a carrying case with all of its accessories.
