HK-2000C integrated digital pulse sensor HK-2000C integrated digital pulse sensor is increased on the basis of HK-2000B on a programmable amplifier, baseline adjustment circuit, A / D converter, serial communication circuit, and two user-friendly integrated times developed using. Piezoelectric principle acquisition signals, digital signal output directly via USB or serial output pulse waveform data. We run on a computer demonstration program included a visual display of the pulse waveform and can waveform amplitude, frequency, etc. to adjust the baseline on a computer screen. This product can be used to detect the pulse rate, noninvasive cardiovascular function tests, pregnancy-induced hypertension detection, TCM pulse diagnosis.
