Description
The Arjo Sonicaid SR2 SR3 are high sensitivity handheld digital Dopplers for screening the fetal heart from as early as 8 to 10 weeks through to labour. Each configuration below is a real, stocked manufacturer bundle.
Main Description
The attached probes are waterproof to IPX7 for high sensitivity detection in normal use and in waterbirth monitoring. The 2 MHz probe is the general purpose choice for all stages of pregnancy, while the 3 MHz probe is preferred by many clinicians in early gestation. Fetal heart rate shows in big numbers with a trace on the high resolution colour display. Data storage on micro SD cards and integrated charging and connectivity support clinic record-keeping. Choose the SR2 with its 2 MHz waterproof probe, or the rechargeable SR2 or SR3 configurations.
