GE MAC 1200 EKG Machine
Call For PRICING
The GE Marquette Mac 1200 is a compact 12-lead ECG system. The MAC 1200 can be configurable for standard electrocardiography without analysis or to include a 12-lead analysis. The system offers a full-page printout and a display showing waveform ECG readings. The MAC 1200 is an easy-to-use system that offers a one-touch operation for acquisition, analysis, storage, and printing. The GE system includes EKG/ECG electrodes, chart paper, and lead wire.
- Full-size keyboard is easy to use and clean
