Description
The Arjo Flexi Dopplex D930 is a compact audio fetal Doppler with a fixed 3 MHz waterproof probe, the frequency many clinicians prefer in early gestation. Departments order it as a single unit against a standard stock code.
Main Description
The 3 MHz probe suits early pregnancy work where the fetal heart is smaller and higher. The compact, lightweight body travels easily between clinic rooms and home visits. LED lights show power and battery status clearly during use. A combined power, off and volume control keeps the unit to a single dial. The easy-clean waterproof probe supports infection control and water birth use.

Why Choose the Flexi Dopplex D930?
Departments standardise on the Flexi Dopplex D930 because the manufacturer publishes the data behind it. The D930 is the 3 MHz half of the Audio Dopplex pair, tuned to early pregnancy rather than general obstetric use.
- Early Gestation Focus – The 3 MHz probe is the choice for first-trimester listening.
- Pool and Bedside – A waterproof probe covers water birth monitoring too.
- No Charger Queue – AA cells keep the unit in service without docking.
