The 3L Calibration Syringe is a device used to check the accuracy of QRS spirometers. It is a 3L syringe that is filled with air and then attached to the spirometer. The spirometer is then used to measure the volume of air in the syringe. The results are compared to the known volume of the syringe to determine the accuracy of the spirometer.
