Description:
<br />
<br />This fetal doppler is designed to meet routine examination requirements for pregant women in hospitals and clinics or at 
<br />
<br />home. The intended use of the unit is detection of the fetal heart rate and fetal heart beat sound listening.It 
<br />
<br />is a high performance model with FHR digital and autocorrelation algorithm for high FHR accuracy.The fetal doppler
<br />
<br />uses ultrasound technology to detect doppler sounds from the fetus as early as 16 weeks of pregnancy to the baby 
<br />
<br />first moment of life.
<br />
<br />Feature:
<br />
<br />Advanced auto-correlation algorithm for high FHR accuracy
<br />
<br />High sensitivity wide beam integrated sensor for reliable detection throughout pregnancy
<br />
<br />Active noise reduction for crystal clear fetal heart sounds
<br />
<br />Low ultrasound output dosage for ultimate safety
<br />
<br />Advanced power management for long battery life
<br />
<br />Elegant and compact design for easy home use
