CONTEC ECG300G Electrocardiograph,Digital 3 Channel 12 lead EKG+Printer

The ECG300G is a sophisticated electrocardiograph capable of collecting 12-lead ECG signals and printing the waveform using a thermal printing system. It supports both AUTO and Manual recording modes, automatic measurement and diagnosis of ECG waveform parameters, and provides prompts for "Lead off" and "Lack of paper". The device also features a multi-language interface, AC/DC power options, selectable rhythm leads, and case database management.

Features

• High-Quality Signal Processing: Synchronous collection of 12-lead ECG using digital signal processing technology with power frequency, baseline, and EMG filters for optimal ECG waveform quality.
• Comprehensive Display: Displays 3/6/12-lead ECG, print mode, sensitivity, paper speed, and filter state on one screen for easy comparative diagnosis.
• Multiple Printing Modes: Offers various printing formats including manual, auto 4×3, auto 3×4+1, auto 3×4, and others. Adjustable waveform length and time print functions meet diverse requirements.
• Auto-Analysis and Diagnosis: Automatically analyzes and diagnoses routine ECG parameters, providing measurement results and conclusions for HR, P-R interval, QRS Duration, and more. Note: The FDA version lacks automatic analysis but can achieve this through free PC software.
• Large Memory Capacity: Built-in memory can store up to 1000 cases, facilitating case review and statistical analysis.
• Multi-Language Support: Interface and reports available in Chinese, English, Spanish, Turkish, Polish, Italian, French, German, Portuguese, Kazakh, Russian, Ukrainian, Serbian, and Slovenian.
