✔ Re-usable hospital grade sensors included!
✔ Monitor output for professional scope display
✔ Simple and safe 9V battery operation
February is Valentine’s Day
month, and what a great time
to think of your heart! Not how many
times it’s been broken, not how many times
it’s fallen head over tails in love, but how it
actually works...and how it’s doing these days!
Use the ECG1C to astound your physician with
your knowledge of ECG/EKG systems. Enjoy learning about the inner workings of the
heart while at the same time covering the stage-by-stage electronic circuit theory
used in the kit to monitor it. The three probe wire pick-ups allow for easy application and experimentation
without the cumbersome harness normally associated with ECG monitors. The documentation with ECG1C
covers everything from the circuit description of the kit to the circuit description of the heart! Multiple “beat”
indicators include a bright front panel LED that flashes with the actions of the heart along with an adjustable
level audio speaker output that supports both mono and stereo hook-ups. In addition a monitor output is
provided to connect to any standard oscilloscope to view the traditional style ECG/EKG waveforms just like you
see on ER... or in the ER! See the display above? That’s one of engineer’s hearts after an engineering meeting!
The fully adjustable gain control on the front panel allows the user to custom tune the differential signal
picked up by the probes giving you a perfect reading and display every time! 10 hospital grade re-usable
probe patches are included together with the matching custom case set shown. Additional patches are available in 10-packs. Operates on a standard 9VDC battery (not included) for safe and simple operation. Note,
while the ECG1C professionally monitors and displays your heart rhythms and functions, it is intended for hobbyist usage only. If you experience any cardiac symptoms, seek proper medical help immediately! (Like I did
after I got the ad deadline date for February from Robin!)
