Two Vintage Map / Medical EKG Calipers Electrocardiogram Map Compass Small
What you are about to bid on is two vintage EKG Calipers. If you are a Physician or Cardiologist you will know exactly how to use these. However if you are a layperson like myself you may have thought these were map calipers. Both of these are well made. There is a mesh gear connection at the pivot, and they open smoothly and evenly. The unused or lightly used pair has a 4 centimeter long ruler attached to it, and it is scaled in centimeters. I am including the leather case with these.
