A 3 litre calibration syringe suitable for use with all Spirometers.

The measurement accuracy of Turbine Flow Heads manufactured by Micro Medical remains unaffected by changes in environmental conditions. In consequence their factory-set calibration remains extremely stable(2) and they do not require routine calibration adjustment. However, in accordance with international guidelines (1) their accuracy can be quickly verified by using a 3 litre calibration syringe.

Below is a summary of the key ATS/ERS 2005(1) recommendations when performing a volume verification for flow measuring devices (such as Micro Medical Spirometers)
  • A volume accuracy check should be performed daily(1)
  • A 3-L calibration syringe should be used(4)
  • This calibration syringe should have an accuracy of +/- 0.5% (15 mL for a 3-L syringe) (1)
  • The syringe should be discharged through the device 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 approximately 6s for the lower flow limit and less than 0.5s for the upper flow limit) (1)
  • The volume at each flow should meet the accuracy requirement of +/-3.5%(1)
