The New MicroLoop 3535

Developed specifically for the professional, the next generation MicroLoop employs Micro Direct's acclaimed precision Gold Standard Digital Volume Transducer which is especially suited to measuring very low flow rates in patients with COPD. The MicroLoop has a class-leading, very high definition paper-white screen and can display both Volume/Time and complete Flow/Volume Loops (using either the open or closed loop test techniques).The instrument can measure up to 36 spirometry parameters and has a database storage capacity for over 1000 patients. Comprehensive full-sized printouts are possible using an external Hewlett Packard or Canon printer (compatible models specified by Micro Direct) or through the optional PC software, Spida 5.
