This prenatal monitoring bundle combines a digital fetal doppler and a reliable digital thermometer, offering a convenient solution for pregnancy tracking at home or in clinical settings. The fetal doppler allows expectant parents and caregivers to listen to fetal heartbeat and view heart rate readings using safe, non-invasive ultrasound technology. Paired with a digital thermometer for quick temperature checks, this set supports routine wellness awareness throughout pregnancy.
Designed with simplicity and clarity in mind, the doppler features a high-sensitivity 3.0 MHz probe, an easy-to-read LCD screen, and a built-in speaker with adjustable volume for clear audio output. The lightweight body and intuitive controls make it suitable for home use, midwifery practice, and mobile maternal care. The thermometer adds an extra layer of convenience for checking body temperature when needed.
This bundle supports pregnancy monitoring but does not replace professional prenatal care. Seek medical advice if readings appear irregular.
