The fetatrack® DD250 offers continuous fetal and vascular doppler in the small clinic, hospital or doctors office. Weighing under 2Kg, the fetatrack® DD250 is a truly portable unit. It will operate from a mains supply or for over 30 hours from its built in rechargeable batteries. The fetatrack® DD250 has all the necessary facilities for accurate antenatal fetal heart rate detection or vascular assessment, in one cost effective and compact unit. The probes are connected to the unit via a long retractile cable, reducing the need to continuously move the unit, and interchanged using a high reliability connector.
