Automatic Upper Arm Monitor

The iHealth KN-550BT is an automatic blood pressure monitor designed for home use. It features a wide-range cuff fitting upper arms from 22 to 42 cm. The device operates on four AAA batteries and connects via Bluetooth 4.0 to iOS 12.0 or later and Android 9.0 or later devices. It meets ESH 2010 performance standards for clinical accuracy.

Upgrade From Manual Or Basic Units

This monitor replaces manual sphygmomanometers or basic digital units lacking irregular heartbeat detection. The jump is worth it when you need automatic inflation, colour-coded result interpretation and long-term trend tracking on a smartphone. It stores up to 99 readings on the device itself with unlimited history in the companion app.

Suits Home Users Needing Wide Cuff

The 22 to 42 cm cuff accommodates most adult arms without buying separate accessories. Heart rhythm disturbance alerts add a safety layer for routine monitoring. Buyers requiring a rechargeable power source or a smaller cuff for slender arms should look at other models. Those needing medical-grade diagnostic features beyond ESH 2010 validation will need professional equipment.
