About DAWEI
DAWEI is a China-based medical device manufacturer group founded in 2006 and headquartered in Xuzhou, Jiangsu, operating as Dawei Medical (Jiangsu) Co., Ltd. The group makes home and clinical health devices — blood pressure monitors, ECG machines, nebulizers, and oxygen concentrators — alongside a dedicated veterinary equipment division, Dawei Veterinary Medical, which designs and manufactures the portable B-mode ultrasound scanners it sells on Amazon under the DAWEI name for farm, field, and small-clinic animal imaging.
DAWEI is one of the few brands with multiple models among our top picks in our portable ultrasound coverage. The DAWEI Professional stood out on the strength of its four-level frequency switching probe (2.5 to 5.0 MHz), a rugged drop-resistant waterproof build, and a 4–6 hour battery that covers a full day of field scanning. The DAWEI S1, built around a 7.5 MHz rectal linear probe, earned top marks specifically for cattle scanning in our animal-by-animal comparison — a specialized transrectal probe geometry the rest of the field doesn't offer. Both ship with a two-year warranty and manufacturer training support, ahead of the typical coverage we see from unbranded competitors in this category.

Why we recognized DAWEI

DAWEI products we rated highly
DAWEI Professional Vet Ultrasound Machine Portable Veterinary Handheld Scanner
The most versatile handheld B-mode scanner in our roundup — four-level frequency switching (2.5/3.5/4.0/5.0 MHz) lets one probe cover pregnancy confirmation and musculoskeletal scanning across most farm and small-veterinary species without a probe swap. A 5.6-inch HD LED display with 256 grayscale levels, drop-resistant waterproof construction, and a 4–6 hour battery round out the case for its place among our top picks.

DAWEI S1 Vet Ultrasound Machine for Pregnancy Veterinary Ultrasound Scanner with 7.5Mhz Rectal Probe
The only scanner in our comparison built specifically for transrectal bovine and equine reproductive work — its 7.5 MHz rectal linear probe resolves early pregnancy far better than a sector probe scanning through the body wall. Five display modes, 32GB internal storage, and a two-year warranty with DAWEI training support make it the correct specialist choice for cattle and horse reproductive medicine.
