11-Piece Steam Cleaner Accessory Kit with Microfiber Cloths, Compatible with SC2, SC3, SC4, and SC5

This is a high-quality fetal heart rate detection instrument that uses the Doppler principle to obtain the fetal heart rate from the pregnant woman's abdomen and presents the fetal heart rate data via voice monitoring, digital display, and other means. You can use it to hear the fetal heartbeat and calculate the FHR for prenatal monitoring and fetal care.

Features: High-sensitivity probe, no radiation, low ultrasound power, safe and highly accurate.

Large LED screen, you can clearly see the fetal heart rate, battery level, and volume.

Equipped with a volume control, you can easily adjust the volume to your liking.

Insert the 3.5mm mono or dual-channel headphone jack into the device's headphone port to listen to the fetal heartbeat. The device's external speaker will be muted, so there will be no audio output.

After hearing a recognizable and rhythmic fetal heartbeat, hold the probe still for at least 5 seconds so the device can accurately measure and display the heartbeat. fetal.

Powered by two AA batteries, supports continuous operation. (Batteries not included)

Note: The normal fetal heart rate range is 120 to 160 bpm. 100-120 bpm and 160-180 bpm are critical intervals that should be monitored. Values below 100 bpm and above 180 bpm should be considered.
