What is the Fetal Doppler FD-A20A?
The Wincom Fetal Doppler FD-A20A is a lightweight handheld fetal heart rate detector for antenatal use. The 35 mm × 28 mm (1.77-inch) LCD displays the fetal heart rate numerically across a 50–240 BPM range, with audible heart sound through the built-in speaker. 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), and the unit weighs just 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.
