EDAN's Sonotrax Pro is a portable ultrasound Doppler, designed for professional use in obstetrics and vascular settings. Ideal for routine examinations, it offers high sensitivity and versatility. It supports high-sensitivity, waterproof, interchangeable probes with frequencies of 2 MHz and 3 MHz for fetal applications and 4 MHz and 8 MHz for vascular applications. The device is supplied without a probe.

The ergonomic, compact and lightweight design makes it easy to carry and simple to use even during long work sessions. The 45×25 mm backlit LCD display allows for a clear display of fetal heartbeat (FHR), with automatic probe detection and built-in battery status indicator. Pulse measurement is accurate, with a sensitivity of 1 bpm and a detection range of 50 to 210 bpm.

Sonotrax Pro features a built-in recorder that allows you to store sounds for up to 480 seconds (4 kHz mode) or 240 seconds (8 kHz mode), with an audio output power of 0.5 W. The device offers both automatic and manual calculation of the fetal heartbeat, with crystal clear sound reproduction for reliable monitoring.

Continuous operation is guaranteed for up to 4 hours, with automatic shutdown after 1 minute of inactivity to optimize energy consumption. Power can be provided via 9V alkaline batteries or with a replaceable 7.4V Ni-Mn rechargeable battery. The full charging time is about 10 hours, while a partial charge of 3.5 hours provides 50% of the capacity.
