Simultaneous Acquisition: Captures all 12 standard leads simultaneously for precise spatial diagnosis despite recording on a 3-channel layout.
Automatic Interpretation: Built-in diagnosis algorithm providing automatic ECG measurement and analysis readouts.
Dual Operation Modes: Seamlessly toggles between fully Automated printing cycles, Manual tracking, and dedicated Rhythm strip recording.
Digital Waveform Display: Generates clean, crisp real-time 12-lead views directly on the integrated 5-inch color display before printing.
Audio-Visual Alarms: Built-in alarm alerts for lead-off status, low battery, and system abnormalities with noise thresholds under 50 dB.
Inbuilt PDF Converter & Connectivity: Allows direct conversion of recorded ECG data into standard PDF format directly on the machine, which can be easily transferred to an external USB flash drive without a PC.
Ultra-Compact Portability: Weighing only 850 grams, it is one of the lightest 3-channel medical-grade devices in its segment.
Massive Connectivity Options: Capable of external printing setups (A4 size printing via standard external deskjet/laser printers) and features optional cloud/server connectivity through Bluetooth/GSM modules.
Small to Medium Clinics & General Practitioners: Perfect for routine resting ECG checks where space is at a premium but 12-lead accuracy is necessary.
Home Healthcare Services & Portable Diagnostics: An ideal field unit for mobile health camps, home visit consultations, and rural health clinics due to its featherweight frame and 50+ ECG battery backup.
Hospital Wards & Triage: Serves as an efficient back-up diagnostic tool for quick cardiac screenings at patient bedsides.
