The Maestros MR900 is a high-performance, digital 12-channel electrocardiograph designed for thorough resting cardiac evaluations. It features a bright 5-inch or 7-inch color TFT touchscreen display (depending on the manufacturing layout batch) with an integrated splash-resistant keyboard. Engineered to capture simultaneous 12-lead acquisitions, it integrates built-in measurement and automated interpretation software algorithms. This allows clinicians to generate quick, accurate diagnostics directly onto space-saving, A4-sized thermal paper layouts or export reports digitally.

Simultaneous 12-Lead Processing: Captures complete cardiac waveform views at the exact same moment to guarantee diagnosis accuracy.
Smart Interpretation Facility: Employs advanced algorithms to provide automatic measurements and preliminary diagnostic interpretation reports.
Dual Operation Controls: Combines a fluid touchscreen interface with a rugged, waterproof alphanumeric function-key layout for quick bedside typing.
High-Capacity Battery Backup: Operates on a heavy-duty Lithium-ion battery system that powers over 50 to 100 complete ECG prints on a full charge.
Flexible Diagnostic Print Layouts:
Auto Mode: 3x4+1R, 3x4+3R, 6x2, or full 12-channel blocks.
Manual Mode: 3-lead (3L), 6-lead (6L), or 12-lead (12L) real-time printing.
Comprehensive A4 Printing: Eliminates the need for multiple small strips by outputting clean, full-width 210mm data formats that mirror standard document archiving requirements.
Robust Connectivity Ecosystem: Offers seamless PC data transfer and memory stick downloads via built-in USB routing. Advanced iterations feature option-ready Bluetooth or GSM cloud server synchronization.
On-Screen Workflow Preview: Offers a 12-lead trace preview on the display before running the thermal array printer, minimizing paper waste from artifact interference.
Hospital Cardiology Wings & Wards: Standard resting ECG diagnostic tests, pre-operative clearances, and bedside charting.
Emergency Cardiac Care Units: Safe deployment alongside emergency treatment setups due to integrated defibrillator isolation shielding.
Outpatient Labs & Diagnostic Centers: High-volume daily patient testing utilizing localized internal patient memory.
Ambulatory & Mobile Health Camps: Fully portable at under 3 kilograms, meaning it easily transitions to off-site medical camps operating without immediate mains power.
