The Micro Medical 3 Litre Spirometer Calibration Syringe is designed to simplify the process of spirometer calibration and ensure that devices are functioning correctly. 

Used correctly, the syringe holds exactly 3 litres of air, which can be passed through a spirometer in line with its maintenance schedule and guidelines.  Each Micro Medical accuracy checking syringe is supplied with a unique certificate confirming ATS/ERS 2005 performance compliance.

Usage recommendations

The following are the recommended guidelines when performing a volume verification for flow measuring devices such as Micro Medical Spirometers ATS/ERS 2005(I):

  • A volume accuracy check should be performed daily
  • A 3 litre calibration syringe should be used
  • This calibration syringe should have an accuracy of ±0.5% (15 mL for a 3 litre syringe)
  • The syringe should be discharged through the device at least three times to give a range of flows varying between 0.5 and 12 litres/second (with 3 litre injection times of approximately 6s for the lower flow limit and less than 0.5s for the upper flow limit)
  • The volume at each flow should meet the accuracy requirement of ±3.5%
