Features automatic shut-down. Automatic shutdown in one minute without signal, economical and energy saving. Ultrasound probe, highly sensitive, easy to find fetal heart. Using digital filtering noise reduction technology can greatly reduce the noise of the instrument, and the output is clearer. Lcd display multi-parameter working mode and fetal heart rate display, clear fhr (fetal heart rate) display. No radiation to detect, low ultrasound power, safer to the fetus.

- Lcd white screen, digital display of fetal heart rate, using ultrasonic doppler detection technology, low output power, can be assured for daily fetal heart monitoring
- Independent probe design, simple operation, high sensitivity and wide beam, 2.5mhz probe to ensure reliable measurement during pregnancy
- The use of digital filter noise reduction technology can reduce other noises except the fetal heart, optimize sound processing, reduce background noise, and make the fetal heart sound clearer
- The autocorrelation algorithm can effectively eliminate the interference of the external environment, suppress the noise in the echo signal, and dynamically and accurately measure
- Two listening methods, earphone/amplifier, high-fidelity speaker, low power consumption design, adjustable volume, it will automatically shut down if there is no operation for 2 minutes, saving energy and reducing consumption
