Polar OH1+ Optical Heart Rate Sensor

The Polar OH1+ delivers precise heart rate monitoring with superior comfort and versatility. Lightweight and unobtrusive, this clip-on sensor features six advanced LED optical sensors and Polar’s proprietary algorithms to deliver accurate readings during swiping runs, swims, and strength sessions, without the hassle of chest straps or bulky watches. It's designed for athletes seeking both comfort and high performance across varied sports and conditions.

Designed for multi-sport use, the OH1+ can wirelessly transmit data via Bluetooth® and ANT+, enabling simultaneous broadcasts to two devices—such as a watch and a fitness app—or be used standalone using its 4 MB internal memory, which stores up to 200 hours of heart rate data for effortless syncing post-workout. It also comes with a convenient swim goggle clip, ideal for accurate heart rate tracking in the water (up to 30 m depth).

Comfort hasn’t been overlooked: the included soft, machine-washable armband fits medium to XXL and secures the sensor snuggly to your forearm or upper arm for stable readings. With up to 12 hours of continuous battery life, OTA updates, and compatibility across iOS, Android, Polar watches, and exercise machines, the Polar OH1+ strikes a perfect balance between convenience, accuracy, and durability.
