Product Review

Includes 1 high quality EKG ECG caliper measuring 11.1 cm/ 4.37 inches from points with a protective sleeve that measures 6 cm/ 2.4 inches.

The sleeve is much longer than others on the market and has a ruler that can be used to measure a 6 second strip or 12 lead EKG. On the back of the sleeve there is a clip that can be used to attach it to a uniform, notebook, or pocket.
