Medical Grade Fetal Doppler BF-610P
Medical Grade Fetal Doppler BF-610P
BF-610P fetal doppler is used to listen to the heartbeat of a developing baby. The doppler emits sound waves that are picked up by a special probe and then amplified so that they can be heard through headphones or speakers. Many expectant parents choose to use a fetal doppler during their pregnancy as it provides reassurance that their baby's heartbeat is healthy and strong. Listening to the heartbeat can also be a bonding experience for both parents and children.
Function
◆ Portable Fetal Doppler mainly applies to detect the fetal heartbeat rate from the 12th week;
◆ Built-in rechargeable battery can work continuously for more than 4 hours;
◆ 3.2'' color TFT can clearly display FHR data or graphic, heart rate graphics, battery indicator, the volume of sound, and synchronous FHR signal;
◆ Store and hold FHR data and graphics for up to 12 hours (for option);
◆ BF-610P built-in thermal printer can synchronously print the FHR curve clearly and delicately;
◆ Alarm function when FHR is out of the normal range or battery power is in shortage;
◆ Probes with high sensitivity can detect FHR and umbilical blood steam and are much easier to interchange;
◆ Various frequency probes for different use.(for option);
◆ Normative collocation: 2.0 MHz
◆ RS-232 port can connect the unit with a computer and store the data.
◆ Software is an option.
