Description
The Arjo Dopplex VP4 XS is a 4 MHz high sensitivity vascular probe for very deep vessels, fitting the Dopplex DMX, D900 and SD2 Dopplers. The unit ships ready for clinical service with standard accessories as listed.
Main Description
The 4 MHz frequency reaches very deep vessels that higher-frequency probes cannot assess reliably. XS high sensitivity construction maximises performance in difficult signal conditions. The probe is interchangeable across the Dopplex handheld range, so one probe serves several units. It is the standard deep-vessel choice for larger limbs and deep arterial work. The probe connects to the DMX for waveform display, or to the D900 and SD2 for audio assessment.

Why Choose the Dopplex VP4 XS Probe?
Clinics keep the Dopplex VP4 XS Probe in service because its specifications are published and checkable. Frequency choice is the whole decision in a Doppler probe, and 4 MHz is the deep-vessel end of this range.
- Depth Coverage – Deep vessels in larger patients need the penetration only 4 MHz gives.
- Shared Inventory – One probe type serves every Dopplex handheld in the department.
- Signal Quality – XS sensitivity helps when flow is weak or deep.
