NDD-2030-2 3-Liter Calibration Syringe
The ndd Medical 3-Liter Calibration Syringe (2030-2) includes both the Spirette Calibration Adapter (2030-3) and FlowTube Calibration Adapter (5030-2), as well as a calibration certificate. It fits the ndd Medical EasyOne Air Spirometer (2500-2A) or ndd Medical Easy On-PC Spirometry System (2700-3).
Your EasyOne does not require calibration, but the accuracy of your spirometer should still be verified on a regular basis. Fortunately, the 3-Liter Calibration Syringe makes verification incredibly easy so you can ensure accurate lung function testing for results you can depend on for diagnosis and treatment.
