The Contec CMS 100G is a compact, digital, single-channel electrocardiograph designed for routine cardiac diagnostics and heart monitoring. It utilizes advanced digital signal processing (DSP) technology to deliver clean, clinical-grade ECG waveforms. Equipped with a built-in high-resolution thermal printing system and a clear 2.7" to 2.8" STN-LCD display, this device allows healthcare professionals to review waveforms, lead status, sensitivity settings, and filters in real time. Its multi-language capability and dual AC/DC power options make it a reliable and versatile tool for mobile and stationary healthcare facilities.

Advanced Digital Filtering: Employs precise power frequency, baseline, and EMG filters to neutralize electrical noise and muscle tremors without causing waveform distortion.
Dual Operation Modes: Supports both AUTO mode (where a single button press handles auto lead-switching, measurement, and recording to maximize efficiency) and Manual mode for custom targeted tracing.
Real-Time Data Annotation: Automatically prints crucial parameters alongside the waveform, including lead marks, sensitivity settings, paper speed, and filter statuses.
Smart Indicator Safeguards: Features clear "Lead off" visual alerts if a sensor detaches from the patient and a "Lack of paper" notification when the thermal roll is empty.
Multilingual System: Accessible user interface and printed report options in English, French, Italian, German, Spanish, Turkish, Russian, and Kazakh.
High-Definition Printouts: The maintenance-free 8 dots/mm thermal printing array renders crystal-clear diagnostic details instantly.
Exceptional Portability: At under 2.5 kg with an integrated carry-handle form factor, it is highly optimized for travel and point-of-care diagnostics.
Excellent Battery Lifecycle: Its high-capacity DC lithium pack easily manages over 50 patient examinations on a single standalone charge.
Defibrillation Proof: Built with strict electrical separation layers (Class I, Type CF) ensuring complete patient and machine insulation even if a defibrillator is deployed concurrently.
Hospitals and Outpatient Departments (OPDs): Ideal for quick, routine triage screenings and initial cardiac evaluations.
Private Medical Clinics & Nursing Homes: Provides a cost-effective, daily workflow diagnostic solution for family physicians and general practitioners.
Emergency Medical Services (EMS) & Field Camps: The robust battery, lightweight frame, and physical durability make it a go-to tool for disaster relief camps and rural health drives.
Bedside Monitoring: Allows clinicians to easily move the machine to non-ambulatory or ICU patients without disrupting heavy equipment.
