Heart Rate Monitor

Optical Heart Rate Monitors (OHRM) are used to measure the heart rate through the subject’s fingertip and can be found in devices such as pulse oximeters. Once the circuit is assembled, EWH's OHRM Kit shows the cardiac frequency through a blinking light. The product teaches students principles of electronics and biomedical engineering through hands-on learning and is ideal for middle/high school and college students, or for students training for careers in electronics, BMET, and healthcare occupations. The Kit includes a bare board and electronics components, which can be reused for multiple assemblies.

Engineering World Health’s Optical Heart Rate Monitor Kit is an educational tool only and should not to be used for any other purpose, including any medical, diagnostic or other laboratory applications.
