BF-610TFT Doppler FHR Detector

Features:

• Portable Fetal Doppler mainly applies to detect the fetal heartbeat rate from the twelfth week;
• Built-in rechargeable battery can work continuously more than 4 hours;
• 3.2'' color TFT can clearly display FHR data or graphic , hear rate graphics, battery indicator, 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 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 option.
