Equiment Details - VD BIO Medisystem

The Contec CMS 300GA is a compact 3-channel ECG machine featuring simultaneous 12-lead acquisition and a 3.5-inch color TFT display. It includes automatic parameter measurement, built-in self-interpretation, and a thermal printer. It stores up to 1000 cases and supports PC connectivity for reporting.
Display: Features a 3.5-inch TFT color LCD that simultaneously displays 3, 6, or 12 leads and displays settings like sensitivity, paper speed, and filter status.
Acquisition & Processing: Simultaneously acquires 12 leads and features high-quality digital signal processing with built-in AC, baseline, and EMG filters.
Self-Interpretation: Automatically measures ECG waveform parameters and offers self-interpretation to assist healthcare professionals in diagnosis.
Recording Modes: Supports both AUTO and Manual recording modes using 80 mm wide thermal paper.

Data Management: Internal memory stores up to 1,000 patient ECG records for easy patient history management.
Safety & Alerts: Equipped with "Lead-off" and "Paper-out" alarms, plus defibrillation-proof protection.
Battery: Built-in rechargeable lithium battery provides roughly 1.5 hours of continuous printing.
PC Connectivity: Optional ECG-Sync software allows you to connect the device to a PC via USB to build an ECG workstation for analysis, reporting, and archiving.
