The UltraTec PD1 is a small, lightweight, high sensitivity pocket Doppler. Its 2MHz fetal Doppler probe is ideal for use by General Practitioner or Midwife for routine antenatal fetal detection. The fetal signal is available to the user via the built in loudspeaker or optional headset with output level controlled by edge mounted volume control. The fetal signals are easily located using the lightweight narrow beam transducer while internal signal processing minimises the noise artefacts.
