Wide-Range Cuff Fit

The iHealth KN-550LT is an upper-arm blood pressure monitor designed for home use. Its integrated cuff accommodates arm circumferences from 8.7 to 16.5 inches, covering a broad range of adult users. One-button operation and automatic body-movement, cuff-wrap and irregular-heartbeat detection make it straightforward for first-time users and seniors.

On-Device Storage and App Sync

The monitor stores up to 120 readings internally, providing a local log for immediate review. Unlimited readings can be synced to the free iHealth MyVitals app for long-term trend charts and easy sharing with a healthcare provider. This dual approach suits households that want both quick on-screen checks and detailed digital history.

Dual Power for Flexible Use

The device runs on three included AA batteries or via the supplied USB Type-C cable, allowing cordless portability or continuous mains power. The wide-angle LED display with colour-coded indicator lights remains readable in low-light bedrooms without backlight glare. Gentle intelligent inflation keeps each measurement comfortable and quiet.

Questions about this item

Will the 8.7-16.5in cuff fit the same arms as my old 22-42cm cuff?

Yes, the 8.7-16.5in range equals 22-42cm, so it covers the same arm sizes as your previous cuff.

How do I know the KN-550LT is measuring correctly after I put it on?

The LED screen shows red, yellow or green indicator lights plus body-movement and cuff-wrap detection icons that confirm a valid reading.

Does the box include the Type-C power cable or only the 3 AA batteries?

Both are included — 3 AA batteries and a USB Type-C power cable ship in the box with the monitor, cuff and manual.
