With a 3.0MHz high-sensitivity probe, the Portable Fetal Doppler 3.0MHz Baby Heartbeat Detector tracks fetal heart rates from 50 to 240 bpm. The LCD backlight shows real-time data clearly during night use. This handheld unit enables consistent home prenatal monitoring through the second and third trimesters.
Key Features
- 3.0MHz Ultrasound Probe: High-frequency transducer provides deep signal penetration for early detection. Captures clear rhythms from the 12th week.
- Intelligent Noise Reduction: Digital signal processing filters background blood flow and internal sounds. Audio remains distinct in high humidity conditions.
- Zero Radiation Construction: Passive acoustic technology prevents ionizing radiation exposure during monitoring. Eliminates thermal risk to the developing fetus.
- 60s Auto-Shutoff: Power-saving circuit terminates battery flow after one minute of inactivity. Saves charge on the required two AA batteries.
- LCD Backlight Display: Digital screen outputs heart rate with ±2 bpm accuracy. Readable under low-light or direct indoor lighting.
Frequently Asked Questions
When can I hear baby heartbeat with fetal doppler?
Detection typically begins between the 12th and 16th weeks of pregnancy. The 3.0MHz frequency captures faint signals earlier than lower-rated 2.5MHz probes.
Is home fetal doppler safe for baby?
This device utilizes low-power ultrasound waves with zero radiation emission. It monitors fetal heart rates without producing harmful biological or thermal effects.
