The electronic sphygmograph

Published:2011/8/23 1:01:00 Author: | Keyword: electronic , sphygmograph

The electronic sphygmograph is shown as the chart.It converts the change of pulse pressure to electric signal through the sensor.Then it is handled by enlarging,shaping,counting, coding and driving.Finally the digitron displays how many times a minute your pulse is pulsing.It is very convenient to use.   (View)
