Hi, I'm empty!
Please fill me with a spirometer, PFT filters, or a calibration syringe.
A-M Systems is proud to introduce our new adjustable aluminum calibration syringe. This Syringe has a locking collar and graduated rod that allows the user to specify the desired calibration volume, from 0.5 Liters to 3.0 Liters. The aluminum syringe comes fitted with a universal connector.
