The World’s Most Advanced Hand Held Spirometer
Developed specifically for the professional, the next generation MicroLoop employs Micro Medical’s acclaimed precision Gold Standard Digital Volume Transducer which is especially suited to measuring the very low flow rates seen in patients with COPD.
The MicroLoop features a high definition color touch screen that can display either a Volume/Time curve, a complete Flow/Volume loop or a child incentive graphical display.
The MicroLoop can measure up to 41 spirometry parameters and has a database storage capacity for over 2,000 patients.
The MicroLoop has a desktop docking station that makes battery charging, connection to a PC for data upload and printing the results to an external printer quick and simple.
Spirometry PC Software is included and provides expanded data storage capabilities and trend analysis.
The versatile MicroLoop spirometer offers a comprehensive range of advanced features normally only seen on expensive pulmonary labs and is shipped complete with all necessary accessories in a sturdy carrying case.
