Airflow Transducer

The SS11LB handheld airflow transducer is intended for human use and can be used to perform a variety of tests relating to airflow and lung volume. The transducer is factory-calibrated to measure airflows within -10 to +10 L/second within ±5%. The transducer has a removable head (RX117A) for sterilization and replacement.

• No calibration syringe is required.
• Airflow measurement is much less susceptible to changes in transducer orientation.
• New tiered airflow head design allows for direct connection to multiple standard pulmonary ID/OD hoses and components without the need for couplers.
• Flow correction that was previously only included in lessons (via syringe) is now in Lessons and BSL PRO analog preset.

Use standard disposable mouthpieces with disposable bacterial filters, or use an autoclavable mouthpiece, depending on your budget and/or lab preference. Direct connection to AFT36 35 mm Filtered mouthpiece. The SS11LB can also be used with the AFT22 Non-Rebreathing T-valve for low dead space requirements, and to monitor expiration and inspiration signals separately.

SS11LB is compatible with BSL 4.1.1 and above or AcqKnowledge 4.4.2 and above.

Older model SS11LA with RX117 is available for systems running BSL 4.1.0 and below or AcqKnowledge 4.4.1 and below (software upgrade recommended), and is the shipping airflow transducer model for Chinese and Russian BSL 3.7 Systems. Use AFT1 Filter + AFT2 mouthpiece with SS11LA flow head RX117.
