For Dads and Grads!
We Put The FUN In Electronics!
Every June we celebrate the special place our father’s hold
in our hearts, so why not show your dad how much he
means by helping him take care of HIS heart? As we age, heart
problems become more and more of a concern, so make sure your father
knows you’re thinking of his health. And face it - dad has enough ties in his
closet, so this father’s day avoid the clichés and give him something he can really
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 our engineers, hooked up to the ECG1C 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!
