3 Liter Precision Calibration Syringe

Providing assured accuracy for calibration verification and linearity checking.

Vitalograph precision syringes provide quick and easy accuracy checks with reliability and fast verification.

The 3L precision syringe can be used with flow or volume sensor systems and is compatible with any manufacturers’ equipment.  Each syringe has a unique serial number and history file with accuracy certified to better than 0.5%.

For flow measuring spirometers, the 2019 ATS/ERS Standardization of Spirometry guidelines recommends daily calibration verification using a 3 liter syringe with a filter attached.

The 3-L precision syringe is recommended for all spirometers as required by ISO 26782:2009.  A range of adaptors is available.

Comes with 5-Year Warranty if registered within 30-days of purchase.

Product Specification


The 2019 ATS/ERS Standardisation of Spirometry guidelines recommend:

“Calibration verifications must be undertaken at least daily using a 3-L syringe cycled at least three times to give a range of flows varying between 0.5 and 12 L/s (with 3-L injection times between 0.5 and 6 s). If an in-line filter is used in spirometry testing, then it must also be used during recalibrations and verifications.”

Yes. The 2019 ATS/ERS Standardisation of Spirometry guidelines recommend:

“A biological control is not a substitute for the use of a calibration syringe. However, operators are encouraged to know their own usual FEV1 and FVC, which allows them to conduct a quick, rough check if they suspect a problem.”
