MasterScreen™ PFT system

Achieve complete pulmonary function testing

The MasterScreen™ PFT system provides instrument hardware for lung function testing from simple spirometry to complete lung function testing.

SentrySuite® software

An IT-compliant SQL database offers new user interfaces for testing, interpretation and reporting.

Accommodating body plethysmograph sizes

Our standard and wide-body (1,350 L) box cabins help test larger patients and accomodate wheelchair-bound patients.

Real-time DLCO gas analysis

The rapid-responding three-gas analyzer measures real-time gas analysis independent of expired flow velocity. 

Lung diffusion during resting breathing

Only MasterScreen PFT can measure DLCO and lung volume during same rebreathing test maneuver.

Large patient range

MasterScreen products offer infant, pediatric and full adult PFT, plus IOS testing.

Optimized bronchial challenge testing

Our optional fully integrated nebulizer system, APS Pro, helps conduct bronchial challenge testing with optimal control.


Inspiratory and expiratory pressures come standard with each MasterScreen PFT with SentrySuite software.

Add-on technologies

Body plethysmography, IOS, APS Pro, P0.1, Rocc and CPET can be conveniently added.

Online communication

Sentry.NET software with the system lets you use the intranet to analyze and interpret the data.
