Carrier Signal Conditioner

The Carrier signal conditioner was designed to work with the Validyne DP-45 and DP-250 Pressure Transducers for accurate pulmonary pressure, volume and flow measurements.  Since the Carrier signal conditioner was designed around the Validyne transducers, you can be sure that measurements are accurate with virtually no drift when compared to competitive products.  Coupled with the Pulmonary Air Flow (PAF), Pulmonary Compliance and Resistance (PCR), and Unrestrained Plethysmography (URP) software analysis modules, DSI can record and analyze data from virtually any pulmonary application.
