Used - Good DYNATECH NEVADA 404A

This device features interchangeable test chambers (typically 3.5 mL and 35 mL volumes) that connect inline with the infusion pump under test. It measures delivered volume over time, calculates flow rates from 0.5 to 1000 mL/hr, and displays results on an analog or digital readout for occlusion detection, accuracy verification, and troubleshooting pump faults.

Key Features

Flow Range: Tests 0.5–1000 mL/hr across low and high flow rates with ±2% accuracy using precision chambers.
Chambers: Dual volume options (3.5 mL for slow rates, 35 mL for faster rates) for comprehensive testing protocols.
Applications: Required for preventive maintenance, annual calibration, and compliance testing of IV pumps per biomedical engineering standards.
