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. Coupled with the Pulmonary Air Flow (PAF), Pulmonary Compliance and Resistance (PCR), Pulmonary Volume (PVO) and Unrestrained Plethysmography (URP) software analysis modules, DSI can record and analyze data from virtually any pulmonary application.
