12 Channel Electrocardiograph

12-channel ECG machine.

  • This product is an ECG machine with 12 ECG simultaneous leads that enable recording the ECG wave shapes with a system of thermal printing.
  • The equipment must be used and taken care of exclusively by qualified staff.
  • High-resolution LCD screen 800 × 600, 1728 printing dots of width. It can print ECG waves of 12 channels.
  • It works with a keyboard or touch screen.


  • Recording and viewing of ECG waveforms in automatic/manual modes.
  • Self-measuring and self-diagnosis of the ECG wave parameters, indications of turned off lead, and lack of paper.
  • Management of the database.


  • Colour LCD screen 800 × 600, touchscreen, and control keys.
  • High-resolution thermal printer (8 dots/mm). It doesn’t need adjustment of any kind. Frequency response of up to 150 Hz.
  • The device can record clear and precise waveforms of 12 channels in real-time and in a continuous manner. On display: lead, sensitivity, paper speed, filter state, etc.
  • In automatic mode, you only have to press a button to start the record.
  • Design with a digital filter to prevent the diversion of the baseline and the CA and EMG interferences.
  • Automatic adjustment of the baseline, optimisation of the record adjustments, rhythm lead available.
  • Control with keyboard and touchscreen to facilitate the device’s handling. The state appears on screen in favour of your comfort.
  • The power system combines AC/CC. This device includes a rechargeable lithium battery, an automatic circuit of protection, and the automatic switch-off time can be set if it doesn’t receive a signal.
  • This equipment registers 150 ECG waves and prints continuously for 90 minutes.
  • The memory of the device can store 1000 patients’ files, which is useful for analysing data and statistics.
  • Elegant and lightweight design.
  • It can record and store data by pressing just one button.
  • Digital signal processor with CA, DFT, and ECG to get a high-quality electrocardiogram.
  • The equipment has the function of measurement, analysis, and automatic diagnosis to facilitate the job of the professional staff and, thus, reduce the workload.
  • The team meets simultaneously 12 ECG channels and analyses with different record modes such as 12×1, 6×2+1, 6×1, 6×2, rhythm row 12, row 10, row 8, row 6, etc. There are different formats for the reports.
  • The device enables to view 3, 6, or 12 lead waves in real-time with different views. There are indications of turned-off lead, lack of paper, etc. Also, the parameters can be detected automatically and a report can be created from the carried out analysis.
  • It can also register waves in manual or automatic modes and the data of the patient are stored in a database.
  • Language: English.
  • Safety classification: Class I, applied parts type CF, defibrillation proof.
  • Protection degree from liquids absorption: IPX0.
  • According to the safety degree when using in environments where there are anesthesia types gases, flammables, mixed with air: this device is not suitable for its use in such environments.
