Feature: The unique design of this ECG caliper allows accurate direct measurement of Heart Rate, wave amplitude, and P-R, QRS, and Q-T intervals.  There is no need to sue an ECG ruler(interval scale) to convert caliper readings: intervals can be read instantly for either 25mm/sec or 50mm/sec ECG paper speed. For added convenience, a metric and starndard ruler are printed on the back of the caliper.
