HK-2000C Integrated Digital Pulse Sensor

Based on the HK-2000B sensor, HK-2000C integrated digital pulse sensor is added program-controlled amplifier, baseline adjustment circuit, A/D converter circuit, serial communication circuitry, it’s easy to be integrated and used by our users. The sensor use piezoelectric principle to acquire signal, output digital signal, that is pulse waveform data outputed directly via USB or serial port.

The product can be used in pulse rate detection, non-invasive Cardiovascular Function Testing, detection in Hypertensive syndrome of pregnancy, TCM pulse diagnosis, and so on.
