Each Calibration Syringe has a label indicating the model, serial number, date and calibrated volume. The calibrated mechanical stop in each Calibration Syringe provides an accurate and repeatable volume standard appropriate for spirometer calibration. The mechanical stop has its corresponding volume calibrated with a volumetric apparatus certified to meet the accuracy requirements of the National Bureau of Standards Circular 602. In addition, each syringe is 100% leak-tested and traceable to NIST standards.
The Calibration Syringes manufactured here at A-M Systems offer users a low-cost method for checking the volume measurements for pulmonary function analyzers. Analyzers need to be periodically checked against a known volume to ensure that they are in calibration. It is poor practice to rely on an internal calibration procedure without a known volume standard.
With regards to volume accuracy, calibration checks must be undertaken at least daily, using a 3-L syringe discharged at least three times to give a range of flows varying between 0.5 and 12 L•s-1 (with 3-L injection times of ~6 s and <0.5 s).
A-M Systems offers the 3-liter size to meet national and international standards and requirements for spirometry equipment.
The 3L calibration syringes must be recalibrated annually to remain compliant with state and national regulations.
Calibration Package: After you receive a new syringe, send in your current syringe for calibration. This eliminates downtime.
Basic Calibration: Send in your current syringe for calibration. Downtime may be up to five weeks.
