Pregnant Women Home Fetal Heart Rate Monitor(English Version U3-02)

1. Measuring range: 60-210bpm2. Material: Plastic3. Voltage: DC 3V4. Output ultrasonic power: less than 20mW5. Power supply: 2 AA alkaline dry batteries (not included)6. Size: about 12x9.3x3.1cm7. Weight: about 250 gramsFeatures:1. LCD white screen, digital display of fetal heart rate2. Using ultrasonic doppler detection technology, low output power, can be assured for daily fetal heart monitoring3. Independent probe design, simple operation, high sensitivity and wide beam, 2.5MHz probe to ensure reliable measurement during pregnancy4. 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 clearer5. The autocorrelation algorithm can effectively eliminate the interference of the external environment, suppress the noise in the echo signal, and dynamically and accurately measure6. Two listening methods, earphone/amplifier7. High-fidelity speaker, low power consumption design, adjustable volume8. It will automatically shut down if there is no operation for 2 minutes, saving energy and reducing consumption
