The SPT-301 Pulse Wave Tonometer delivers arterial waveforms straight from skin contact, with no catheter and no insertion, making it a proven tool for accurate cardiovascular monitoring.
The SPT-301 uses Millar sensing technology to capture detailed carotid, femoral or radial artery waveforms with clarity and consistency.
Seamlessly connect the tonometer to standard blood pressure monitors or DAQ setups using Viking-compatible cables (e.g., TEC-10D, PEC‑10C). Once integrated, it outputs real-time waveforms and enables dual-sensor setups to calculate pulse wave velocity and arterial stiffness.
The SPT-301 supports critical assessments like pulse wave velocity and augmentation index measurements, commonly used in evaluation heart failure, hypertension, arterial stiffness, and stroke risk, and it is cited in numerous clinical studies.
The Millar SPT-301 Pulse Wave Tonometer can be used to evaluate cardiovascular function in various health conditions including:

Millar’s SPT-301 Pulse Wave Tonometer measures arterial pressure waveforms from the arterial, femoral or radial artery, which is used to assess cardiovascular function including pulse wave velocity (PWV) and arterial stiffness.
No. Due to variables in placement and applied pressure, the SPT‑301 isn’t calibrated for continuous absolute arterial pressure.
Yes. You can connect the tonometer to the PCU‑2000 Control Unit or units like the MPVS Duo™ via PEC‑10C interface cables for seamless signal acquisition.
Yes. The SPT-301 can be used repeatedly. It can be cleaned and sterilized according to protocol. It is not for single use.
