Elevate your training precision with the Polar H9, a dependable and budget-friendly ECG chest strap designed to deliver accurate heart rate tracking even during high-intensity workouts. Built with Polar’s advanced electrical heart rate (ECG) technology, the H9 provides real-time, fast-response readings that are not affected by temperature, skin tone, or water—including swims—making it a versatile choice for all athletes. Powered by a replaceable coin cell battery, it delivers an impressive up to 400 hours of usage—that’s over one year of daily one-hour training sessions.
Connectivity is seamless: the H9 provides simultaneous Bluetooth, ANT+, and 5 kHz transmissions for smartphone apps, Polar watches, gym equipment, and third-party platforms. The ergonomic textile strap is soft and snug, easily machine-washable, and gentle on the skin. After your workout, just detach the sensor pod and toss the strap in the wash for easy maintenance. Fully waterproof to 30 m, the H9 stands up to intense sweat sessions, pool laps, and outdoor excursions without skipping a beat.
Whether you're syncing with your favorite fitness app or using Polar Flow to analyze your training, the H9 delivers trusted performance day after day. It’s ideal for athletes looking for simplicity, accuracy, and versatility without the higher price tag—Polar's acclaimed precision and rugged engineering, all for less.
