Huntleigh Sonicaid Digital SR2 – Fetal Doppler 2MHz

Accurate, clear, and advanced fetal heart rate monitoring with digital precision for confident prenatal care.

Product Overview

The Sonicaid SR2 Digital Doppler is a high-performance handheld fetal Doppler designed to deliver accurate fetal heart rate (FHR) detection with both audio and visual feedback. Ideal for midwives, GP practices, and obstetric care settings, the SR2 combines advanced digital technology with ease of use for reliable monitoring throughout pregnancy.

Featuring a high-sensitivity 2MHz waterproof probe, the SR2 is particularly suited for general-purpose use across all stages of pregnancy, offering deeper signal penetration where required. The device provides both large numeric FHR readings and real-time waveform (trace) display on a high-resolution colour screen, supporting improved clinical interpretation.

With integrated data storage, USB connectivity, and Dynamic Digital Noise Reduction (DDNR), the SR2 enhances signal clarity while enabling efficient documentation and workflow integration.
