Trigno EKG Biofeedback Sensor
Add EKG signal recording to your physiological measurements
This biofeedback sensor is ideal for research involving physical activity, such as studies for childhood obesity, home monitoring and performance athletics. The onboard accelerometer can be used to gauge body movements or to identify subtle chest movements corresponding with breathing rate.
Connects to industry standard snap lead electrodes
Easy processing of heart rate, variability and similar functions
Built-in triaxial accelerometer
2.4 GHz transmission
