U90B uses the clinically established oscillometric measurement method with a dual motor system and dual sensors that verify each reading. It is FDA 510(k) cleared, CE MDR certified and ISO 13485 certified, and has been independently tested by an AAA-level hospital with published clinical validation.

Small differences in how tightly a cuff is wrapped, where it sits on the arm and how high it is held can move a reading up or down. That is why the same person can get different numbers minutes apart. U90B standardises the process so those differences are largely taken out of your hands.

Yes. There is no wrapping, no fastening and no repositioning. You slide your arm in, press Start, and the monitor adjusts around your arm on its own before it measures.

Yes. The arm-in design was built specifically so one person can take a consistent reading alone, without a second pair of hands to hold or tighten a cuff.

The integrated arm-fit system suits the great majority of adult upper arms. Because the monitor closes around your arm itself rather than relying on a fixed wrap length, it accommodates a wide range of arm sizes.

No. The dual motor system applies controlled, stable pressure and releases as soon as the measurement is complete, so the squeeze is brief and even rather than tight.

About a minute from sliding your arm in to seeing your systolic, diastolic and pulse figures on the display.

Yes. More than one person in a household can use the same monitor, and readings can be kept in separate profiles in the app so each person's history stays their own.

No. Every reading shows on the monitor's own large display. The app is optional and only adds history and trends over time — choose the Bluetooth version above if you want it.
