Features:
Handheld and Practical: It's designed for pregnant women to check FHR daily. The pregnant women can operate by themselves, hear the fetal heart sound, and calculate FHR to achieve the purpose of pre-monitoring the fetal heart rate.
Accurate Measurement: The use of autocorrelation algorithm can effectively eliminate the interference caused by the external environment, suppress the noise in the echo signal, improve the response speed, and ensure accurate measurement results.
High-Sensitivity Probe: The wide-beam and probe with high-sensitivity can ensure reliable measurement values throughout pregnancy.
Intelligent Noise Reduction: The use of digital filter noise reduction technology can greatly reduce the noise of the instrument, and the output heart sound will be clearer.
LCD Display: The large LCD screen makes the reading clearer, convenient and worry-free.
