iHealth KN-550BT Upper Arm Monitor

The iHealth KN-550BT is a clinically accurate blood pressure monitor designed for adults who want reliable home readings. It operates on four AAA batteries and features a large multi-colour backlit display that shows results with colour-coded indicators. The device stores up to 99 readings directly on the monitor.

Wide-Range Cuff Fits 22-42 cm Arms

The single specification that determines fit is the cuff circumference range of 22 to 42 centimetres (8.7 to 16.5 inches). This wide-range cuff accommodates most adult upper arms without needing a separate accessory. If your arm measurement falls outside this range, the cuff will not provide accurate results.

Suits Adults Tracking Heart Health at Home

This monitor suits users who want Bluetooth 4.0 connectivity to the free iHealth app on iOS 12.0 or later and Android 9.0 or later for unlimited data tracking. It also alerts for heart rhythm disturbances during measurement. Buyers who need a mains-powered unit or a cuff for arms larger than 42 cm should look at other options.

Questions about this item

What does the 99-reading limit on the monitor itself mean for daily tracking?

The device stores up to 99 measurements locally; older readings are overwritten once that limit is reached, while the iHealth app keeps an unlimited history.

How does Bluetooth 4.0 affect data transfer to the smartphone app?

Bluetooth 4.0 pairs the monitor with iOS 12.0+ or Android 9.0+ devices, syncing each reading to the free iHealth app after measurement.

Will the 22-42 cm cuff fit my arm without an extra accessory?

The included wide-range cuff covers arm circumferences from 22 cm to 42 cm, so most adults can use it straight out of the box.
