KWL-B01 monitor and upper-arm cuff, three-quarter view with white housing and gray display surround.

One button. One clear reading.

Automatic inflation. One-button Start / Stop. Large LCD display. Automatic shutoff.

KWL-B01 LCD close-up showing SYS, DIA and PUL labels, date and time; readings are illustrative.

Your numbers at a glance.

The large LCD keeps systolic pressure, diastolic pressure, pulse rate, date, and time easy to read in one place.

SYS — Systolic pressure

DIA — Diastolic pressure

PUL — Pulse rate

A color-coded pressure-level indicator provides an additional visual reference alongside each reading. It is not a diagnosis.

Built for two.

Two separate user profiles can each store up to 99 readings, making it easier to follow measurements over time without mixing histories.

The monitor can also display the average of the three most recent readings.

2 users. 99 readings per user. 198 total stored readings. 3-reading average.

Guidance you can hear.

Optional voice prompts guide you through the measurement process and can read measurement results aloud.

Voice can be turned on or off from the monitor settings.

More information with every measurement.

If the monitor detects an irregular heartbeat pattern during measurement, an indicator appears on the display.

The irregular-heartbeat indicator is informational and is not a diagnosis. Consult a healthcare professional if you have questions about your readings or heart rhythm.

Designed for upper-arm measurement.

The included cuff fits adult upper arms measuring 22–32 cm (8.7–12.6 in).

For best results, position the lower edge of the cuff approximately 2–3 cm above the elbow and keep your arm supported at heart level.

A better measurement starts with a better routine.

1. Sit quietly. Avoid eating, smoking, or exercise immediately before measuring. Rest for about 10 minutes before taking a reading; allow about 30 minutes after intensive exercise.

2. Position the cuff. Place the cuff on your bare upper arm, approximately 2–3 cm above the elbow. Keep it snug enough to allow about one finger underneath.

3. Stay still. Sit with your back supported and your arm at heart level. Press Start, and avoid moving or talking until the measurement is complete.
