MicroLab 3500 Spirometer

Product Overview


Developed specifically for the professional, the next generation MicroLab 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 MicroLab 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.

A built-in high resolution printer quickly delivers hard copy results; however full page printouts are possible using an external Hewlet Packard or Canon printer (compatible models specified by Micro Direct). A new child incentive graphical display is featured and an optional Airway Resistance measurement module is offered. A comprehensive range of advanced features normally only seen on more expensive laboratory based equipment are included (see features and specifications).

As an option to MicroLab we offer Spida 5: a 32-bit PC based Spirometry software package. With a very user-friendly, modern multi-window, visual interface and many new advanced features. Up to 41 spirometry parameters are measurable, Closed loop test technique and the overlaying of previous curves for comparison are now possible.

Extensive search facilities and powerful comparative and long term trending of results are only some of the features. Spida 5 will connect with the SMS text entry keypad versions of MicroLab (ML3500) MicroLoop (ML3535) and the Gold standard transducer versions of MicroGP (MS07) MicroDL (MS08) MicroDiaryCard (MD02), and MicroPlus (MS03). Spida 5 is compatible with Microsoft Windows 95, 98, 2000, Me, XP and NT.
