                                    VT305                                     

Portable Gas Flow Analyzer


       The VT305 Portable Gas Flow Analyzer is the quick and easy way to test medical gas flow and pressure devices. This versatile tool evaluates the performance of a wide variety of devices and multiple ventilator parameters.
        The VT305 features internal sensors to make connecting to medical devices a fast and easy process. The four-button front-panel control makes switching to the best view of measured data simple. Onboard graphing capabilities allow users to view waveforms right on-screen, and measurements (numeric and waveform data) can be stored on the unit’s 2 GB SD card with a simple buttontouch. Users can upload these measurements to a computer for viewing or printing using the included Windows-compatible utility program.The base unit measures flow, pressure and oxygen concentration. It also measures gas temperature within the on-board flow-measurement channel to make correction to selectable gas  standards easy.

         Additionally, the VT305 is compatible with Ansur software, which streamlines the standard  work for testing medical devices through ready-to-use templates and easy drag-and-drop template  modifications. The automation provided by the Ansur software helps reduce human error, improves

 consistency in data collection and reporting, and ensures compliance to OEM requirements.
