For this guide, we considered home blood pressure monitors meant for use on adults. You can find four types of basic blood pressure monitors for home use:

• upper-arm monitors that automatically inflate at the touch of a button
• upper-arm monitors that require the user to pump a bladder to inflate them manually
• monitors that measure blood pressure at the wrist
• fingertip monitors

We chose to focus on portable wrist monitors with that automatically inflate because, for most people, they are easier and more convenient to use. And there is the most important element of a blood pressure monitor is its accuracy. This is determined by the blood pressure machine itself (called a sphygmomanometer) and the size of the cuff; if the cuff is the wrong size, your reading will be off. In addition, the conditions under which you measure your blood pressure—from the time of day to your body position to whether you’ve had caffeine—can affect your readings, no matter the machine.

For most people, home blood pressure monitors provide sufficiently accurate readings. To that end, consistency is nearly as important as accuracy: For tracking trends in blood pressure over time, obtaining consistent readings is largely more important than getting a perfectly precise reading each time.

There’re more to be considered:

• On-device data storage:  Data storage on the device: It is very important to track the health trend over a period of time, so you need enough data points to check. The model we are looking for can store readings for at least a few weeks.
• Irregular heartbeat detection: Consistently irregular pulse readings are something you should discuss with your doctor, so we considered it a bonus if a monitor could pick up on them.
• Screen readability: We looked for large, easy to read displays that can show result crystal clear.
• Power source: Some monitors run on replaceable batteries, whereas others can be recharged via USB.
• Warranty terms:  1 year warranty is ideal for this health medical product.
