Life sciences device testing often requires stable, bi-directional flow measurement with minimal circuit impact. The TSI 4000 Series delivers low pressure drop and fast response, helping biomedical and research teams capture reliable data across ventilators, anesthesia machines, oxygen therapy devices, and lab setups.

Why the 4000 Series fits life sciences:

  • Wide dynamic range supports adult, pediatric, and neonatal profiles
  • Bi-directional measurement suits inhalation/exhalation phases
  • Low pressure drop helps preserve circuit performance
  • Analog and digital outputs integrate with DAQs and service carts
  • Compact design supports bedside and benchtop use

Typical applications:

  • Ventilator flow verification and trigger testing
  • Anesthesia circuit flow assessment and leak checks
  • CPAP and oxygen concentrator validation
  • Respiratory research involving mask and circuit characterization

Practical integration:

  • Use analog outputs for quick tie-in to existing DAQs.
  • Leverage digital connectivity to capture temperature or pressure (model-dependent).
  • Pair with standard adapters to speed circuit setup.

Maintenance and workflow tips:

  • Establish reference checks at intervals defined by your program.
  • Document station configuration for repeatable results.
  • Align data file names with device IDs and operators to streamline traceability.

Whether you are verifying field performance or conducting baseline studies, the 4000 Series provides the responsiveness and usability life sciences teams need. Its balance of performance, connectivity, and portability makes it a dependable choice for daily work in clinical engineering, R&D, and production support.
