Jumper JPD-100S5 Radiationless Baby Fetal Doppler Heart Beat Detector Monitor - White + Pink
Overview:
- Ultrasonic emitting frequency: 2.5MHz±3%
- Overall sensitivity at the 200 meters of distances: ≥90dB
- Effective area of the ultrasonic transducer active element: 1.57cm2
- Ultrasonic output power: ＜5mW/cm2
- FHR test range: 30 bpm ~240 bpm
- Battery type: 9V alkaline battery
- Ultrasound gel specification: density = 1.0g/cm2, speed ≤1.7m/s
- Acoustic impedance: ≤ 1.7x105g/cm2.s, attenuation ≤0.02db/mm
- Peak of negative acoustic pressure: p-<1MPa
- Output beam sound intensity: Iob＜20mW/cm2
- Ispta＜100mW/cm2
- Backlight turns on when there is fetal heart signal; Backlight turns into white light when the fetal heart rate is between 120~160bpm; Backlight turns into orange light and the fetal doppler sounds a warning when the fetal heart rate is less than 120bpm or more than 160bpm.
- No battery indicator shows in the lower right corner when the battery is at a high level; Batter indicator comes out when the battery is at a low level; When there is no cardiac value showing, but only battery indicator, then you need to replace the battery.
- In order to hear clearer, suggest not use headphones and speaker at the same time.
- Now you can safely listen to the prenatal sounds and monitor the heartbeat of your unborn baby in the comfort of your own home.
- Enjoy the amazing experience of hearing your baby's heartbeat, hiccups & kicks. Even record them to share with family & friends.
