Measuring BP from both radial and ulnar may result in overestimation due to the different depth of the arteries.

H2-BP measures BP from a single stable signal of the radial artery only.

The smallest medical bp monitor in the world
Wristband blood pressure monitor

H2-BP measures BP from a single stable signal of the radial artery only.

  • Measuring BP by compressing the radial artery only.
  • The radial artery sits right on the radial bone.
  • BP can be measured even with a small amount of pressure to block the radial artery.

Reliable with stable signal

  • Only single stable signal is detected from the radial artery.
  • Eliminate the disrupting signal from ulnar artery.
  • H2-BP has been approved as a medical grade device by the clinical study by the university hospital with the tolerance within +/- 5 mmHg margin.

Comfortable and user friendly

  • While measuring BP, ulnar artery is not blocked, therefore the blood circulation continues.

How to use

1. Cuff Setting

     Height adjustment

  • Put the adjusting pin into the hole on the band as shown below
  • Push or pull while pressing the adjusting pin so that the fixed hole will be positioned at the measured number (A~D)

     Cuff position adjustment

  • Adjust the cuff position by inserting the fixing pin according to the number (①~⑦)

2. Wearing

  • Find the strong pulse point on the radial bone
  • Wear it as the cuff is located on that point

3. Measuring


  • Raise your measuring arm from the straight position and set the height with the heart
  • Lightly clench your fist and try not to put pressure on your hand
