What is the Fetal Doppler FD-A20B?
The Wincom Fetal Doppler FD-A20B is the pink-trimmed configuration of the FD-A20 handheld fetal heart rate detector. The 35 mm × 28 mm (1.77-inch) LCD shows the fetal heart rate numerically across a 50–240 BPM range with on-device volume control and charge indicator, and the built-in speaker reproduces the fetal heart sound aloud. The 2.5 MHz continuous-wave ultrasound probe (operating frequency 2.5 MHz ±10%) meets established safety limits (P− <0.5 MPa; Isb <10 mW/cm²; Ispta <50 mW/cm²), the probe docks in a side clip when not in use, and the unit weighs 150 g including probe. Wincom positions it for listening to the baby from the 12th week of pregnancy. KRIMS Meditech Solutions Limited supplies this device with delivery and user orientation, with full after-sales support.
