The Bistos BT-250L obstetric Doppler is used to listen to and monitor fetal heartbeats during pregnancy examinations. It detects heartbeats from the 10th week of pregnancy and displays the heart rate on a wide color LCD screen.

The waterproof 2 MHz probe enables both audio and visual monitoring. The device records the patient ID, supports multiple languages and includes an on-screen user guide, a 450-hour trend function, a speaker with adjustable volume and a headphone output. The rechargeable battery supports continuous operation for up to 5 hours, and the device switches off automatically when not in use.
