This kit is perfect if you do not already have an interface as it contains all you need to measure heart rate. Our Hand-Grip Heart Rate Monitor is ideal for determining a person’s heart rate while mobile or stationary. With this sensor, heart rate can be monitored during, or after, exercise. The sensor consists of wireless hand grips and a receiver module that plugs into any of our data-collection devices. The hand grips sense the electrical signals generated by the heart. For each pulse detected, a signal is transmitted to the receiver module, and the individual’s pulse rate is calculated.
