The Samsung Z20, the US name of the HERA Z20, is a premium ultrasound system for advanced obstetrics, gynecology and maternal-fetal medicine. Its cart carries a 27-inch OLED monitor and a 15.6-inch touch screen, and its fetal tools include HeartAssist™ and BiometryAssist. It sits in the HERA Z Series with the HERA Z10, which inherits its AI-based workflow tools and adds advanced beamforming.

What to check when buying a used Samsung Z20
Inspect every probe's housing, lens and cable
A cracked housing keeps a probe from being cleaned properly, and compromised insulation on a probe or cable carries an electric-shock risk.
How: Look for cracks in the housing, scratches on the lens and wheel marks on the cable, and send any probe in doubt for electrical safety testing, which is not a user test.
Confirm the MI and TI display while scanning
The Z20 shows the mechanical and thermal indices automatically in real time, so a missing index is a fault to resolve before purchase.
How: Scan with a probe connected and confirm that the mechanical index and the thermal index both appear on the monitor.
Check the probes' cleaning agents and gels
Only disinfectants marked compatible are for use on the Z20's probes, and gels or couplants containing oil-based lotions or alcohols are not.
How: Ask which disinfectants and gels each probe was reprocessed with and check each against the compatible list, noting that some validated agents can stain the transducer surface without affecting acoustic performance or image quality.
Test the electronic wheel locks from both ends
The wheel locks are electronic, so a fault in either control can leave the system unable to lock in place or to release.
How: Operate the lock control at the front and at the back of the system, and confirm the wheels lock and release from each.
Common questions about the Samsung Z20
Is the Samsung Z20 FDA-cleared?

A second clearance, K252018, dated January 5, 2026, includes the Z20, HERA Z20e, HERA Z20s, R20, HERA Z30 and R30, and adds an ophthalmic clinical application.
Which Samsung Z20 features are optional?
Features marked optional on the Z20 may require an additional purchase.
They include MV-Flow™ and EzVolume™; the fetal tools 5D CNS+™, 5D Limb Vol.™, MPI+, Live ViewAssist™ and QualityCheck™; the fertility tools 2D Follicle™, 5D Follicle™ and UterineAssist™; E-Cervix™ and LaborAssist™ for labor and delivery; and S-Detect™ for Breast, IOTA-ADNEX and IOTA-SRrisk.
