Description
The MX1E Series Fetal Doppler is a clinically tested prenatal monitoring device designed for home and clinical use, enabling expectant parents and healthcare providers to safely listen to and track a baby’s fetal heart rate (FHR) from the 16th week of pregnancy onward. It uses 2.5MHz ultrasound technology to deliver clear, reliable FHR readings with minimal noise, ensuring a comfortable and reassuring prenatal experience.
The series includes two configurable models to suit different user preferences:
- MX1E(Rechargeable Lithium Version): A convenient, eco-friendly option with a built-in 3.7V rechargeable lithium battery, ideal for long-term home use.
- MX1F(AAA Battery Version): A portable, budget-friendly option powered by 3×AAA batteries, perfect for travel or users who prefer replaceable power.
Both models feature a high-resolution TFT display to show real-time FHR values, waveform visualization, and battery status, plus adjustable volume and a 1-minute auto power-off function to save energy.
