The Contec ECG 1200G Digital 12-Lead Electrocardiograph Monitor is a clinical-grade cardiac diagnostic device engineered for hospitals and medical clinics that demand speed, accuracy, and reliability. By capturing all 12 ECG leads simultaneously in a single acquisition, it eliminates the need for sequential lead recording — reducing patient preparation time and delivering comprehensive cardiac data without delay.
Touchscreen Display & Ease of Use
At the centre of the ECG 1200G is an 8-inch TFT colour LCD touchscreen with 800 x 600 pixel resolution and LED backlight, offering sharp, clear waveform visualisation in real time. Quick-access buttons and an intuitive touch interface keep operation simple for clinical staff, while multiple switchable interface languages make the device adaptable across diverse healthcare environments.
Three Recording Modes for Every Clinical Workflow
The ECG 1200G supports three dedicated recording modes:
- Auto Record — automatically selects leads, records waveforms, and performs measurement and analysis without manual intervention
- Rhythm Record — continuously records and analyses rhythm strips for ongoing cardiac monitoring
- Manual Record — gives clinicians direct control over lead selection for customised recording protocols
All recording is handled by a built-in thermal printing system using 210mm x 30m roll paper, with paper speeds from 5mm/s up to 50mm/s.
Automatic ECG Measurement & Analysis
The device automatically calculates a comprehensive set of diagnostic parameters — HR, P-R interval, P Duration, QRS Duration, T Duration, Q-T interval, Q-Tc, P axis, QRS Axis, T Axis, R(V5), S(V1), and R(V5) + S(V1) — providing clinicians with objective, consistent data to support accurate cardiac diagnosis at the point of care.
Patient Safety
The ECG 1200G is classified as a Class I CF applied part and includes built-in defibrillation and pacing protection circuits. Patient current leakage is kept to just 10µA, with an enduring polarization voltage of ±500mV and a noise level below 15µVp-p — meeting the safety requirements for direct patient contact in clinical settings.
Flexible Power Supply
The device operates on AC power (100–240V, 50/60Hz) for fixed clinical use, and includes a built-in 14.8V, 3700mAh rechargeable lithium battery for cordless or mobile operation within healthcare facilities.
