Zoncare U30 3-Channel ECG Machine

The Zoncare U30 is a compact, 3-channel digital electrocardiograph with an integrated thermal printer, designed for routine resting ECG acquisition in clinics, hospitals, and mobile care settings. It supports 12-lead synchronous acquisition and display while recording 3 channels simultaneously, pairing a 5-inch high-resolution LCD screen with a grid background and shortcut-key waveform switching for efficient bedside operation.

The U30 is built around a 32,000 Hz sampling rate, a 24-bit A/D converter, and a 0.01–350 Hz ultra-wide frequency response—parameters intended to support signal capture across pediatric through elderly patients. CMRR is specified at ≥115 dB, and the system includes pacemaker detection within the acquisition workflow.

The system stores more than 1,000 patient records locally, supports USB and Wi-Fi report transmission, and can connect to external printers, mice, and keyboards through 2 USB ports and an RS232 port. Reports can be exported in PDF, PNG, JPG, GDT, DICOM, XML, HL7, or ZQ ECG formats, and the built-in thermal printer supports roll paper and Z-fold paper. An optional lifting trolley and waterproof, pressure-proof suitcase support cart-based and mobile deployment.

Regulatory status: Zoncare states that its products are certified by NMPA, CE, FDA, and ANVISA depending on the model and market. The U30 user manual references compliance with EN 60601-1:2006+A1:2013 and IEC 60601-2-25, with a Type I CF safety classification. A 2022 FDA import alert referencing Wuhan Zoncare cited failure to list under 510(j) or provide 510(k) notification for an ECG device; the specific model involved and current status should be confirmed directly with Zoncare before U.S. purchase. No independent peer-reviewed clinical validation study specific to the U30 was identified in the public literature during preparation of this page. Availability, labeling, and cleared claims vary by market.

Key Features & Benefits

12-Lead Synchronous Acquisition with 3-Channel Printing

The U30 acquires and displays all 12 leads simultaneously on a 5-inch high-resolution LCD with grid background, while printing 3 channels at a time on the integrated thermal printer. Built-in print layouts include 3×4, 3×4+1R, and 1×12 formats, and external print/output layouts add 6×2 and 6×2+1R options—allowing the report format to match departmental preferences.

32,000 Hz Sampling, 24-Bit A/D, and 0.01–350 Hz Bandwidth

The 32,000 Hz sampling rate, 24-bit A/D converter, and 0.01–350 Hz ultra-wide frequency response are intended to capture signal components across pediatric and elderly patients. CMRR ≥115 dB supports common-mode noise rejection, and the system includes multiple shortcut keys for adjusting paper speed, gain amplitude, filter settings, sampling mode, patient ID, and rhythm. These are signal-chain specifications—clinical value depends on proper electrode placement and clinician review.

Pacemaker Detection and Report Preview

Pacemaker detection is supported for patients with implanted devices, with the user manual directing clinicians to activate PACE Detection when recording pacemaker patients. A report preview function allows the clinician to confirm signal quality, adjust waveform display, and edit interpretations before printing, supporting efficient review and reduced paper waste.

1,000+ Record Storage with Multi-Format Export and Wi-Fi

The U30 stores more than 1,000 patient records locally, supporting paperless records and electronic case storage. Report management functions include preview, query, editing, printing, and transmission, and historical reports can be queried by time and transferred. Export formats include PDF, PNG, JPG, GDT, DICOM, XML, HL7, and ZQ ECG, and the system supports Wi-Fi and wired internet connectivity alongside USB disk transfer.

Built-In Thermal Printer with Roll and Z-Fold Paper Support

The integrated thermal printer supports roll paper and Z-fold paper, and the system also supports an external printer for additional workflow flexibility. Multiple layout display options support built-in printing in 3×4, 3×4+1R, and 1×12, and external output in 3×4, 3×4+1R, 6×2, 6×2+1R, and 1×12.

Peripheral Support and Optional Mobile Accessories

The U30 supports 2 USB ports and an RS232 port, with compatibility for external printers, mice, keyboards, USB disks, and card readers. An optional lifting trolley supports cart-based deployment, and an optional waterproof and pressure-proof suitcase supports field and mobile use.
