Heart Rate Monitor for Athletes
We designed the COROS Heart Rate Monitor to deliver precise heart rate data without the restriction of a chest strap. Worn on the upper arm, this optical heart rate monitor uses advanced sensor technology to provide stable, real-time readings during running, cycling, strength training, and high-intensity workouts.
The secure, adjustable band ensures a consistent fit for maximum accuracy, while Bluetooth connectivity allows seamless pairing with COROS watches and compatible fitness devices. With up to 38 hours of battery life, it’s a reliable, comfortable solution for athletes who want accurate heart rate tracking in every session.
SLEEK & SNUG
Simpler to wear than a chest strap, our soft fabric band lays flat around your arm and locks in place with its textured surface. The low-profile design prevents snagging on clothes or gym equipment, allowing you to forget you're even wearing it.
Flexible Fit
Set the perfect placement and tension on the durable elasticated band by simply sliding the buckle until it feels snug. The secure velcro enclosure enables you to quickly remove the sensor to easily wash the band.
Advanced HRM Sensor
Our latest generation multi-channel optical sensor provides high signal quality. Housed in a tough yet sleek body and protected under a scratch-resistant cover, our advanced sensor will deliver reliable and accurate heart rate data for years.
SUPERIOR FIT
Optical heart rate sensors work best when they're held securely against the skin. Our band is designed to cradle the sensor flush against your arm to prevent external light from getting in to keep the signal quality strong, no matter your activity.
Lasting Power
With 38 hours of full operation or 80 days of standby on a single charge, the COROS Heart Rate Monitor is built to endure. View the battery level on your COROS watch or app and use the magnetic cable to quickly recharge.
Wear Detection
With built-in wear detection, the COROS Heart Rate monitor automatically powers on and off based on when it is worn. Allowing you to automatically connect to your paired devices every time you start a workout.
Multiple Connections
Designed to work seamlessly with your favorite COROS watches and app, it can also simultaneously pair with up to three devices, including non-COROS watches and other Bluetooth-compatible indoor trainers, bike computers, and more.
why the arm
Optical heart rate sensors work by using light to measure blood flow in capillaries beneath the skin. The top of your wrist is a convenient place for a watch, but is a challenging location for even the best sensors. Wearing on the arm offers our optical sensor an optimal amount of blood flow to gather heart rate data with accuracy equivalent to that of a traditional chest strap.
