Book a DemoA single-channel laser Doppler flowmeter used with a specialized fiber optic probe (purchased separately) to measure blood cell perfusion in the microvasculature of tissues and organs.
The Blood FlowMeter supports invasive and or non-invasive specialist disciplines with a range of probe types and probe formats.
The Doppler flow probe can also directly stream real-time recordings toLabChart采集和分析软件(separ购买ately) via USB digital output and the Blood FlowMeter Device Enabler add-on software (supplied).
Alternatively, it has two outputs that provide analog data that can be recorded via a PowerLab data acquisition unit. Speak with yoursales representativeas to which connection option is best for your research.
