DBP-81E4
Joytech / OEM
The Joytech DBP-81E4 Wrist Blood Pressure Monitor redefines portable health monitoring by combining clinical-grade accuracy in an exceptionally lightweight and compact design. Weighing only 114 grams, it is engineered for users who demand reliable tracking without compromising on convenience. With advanced features like a motion detection indicator, WHO-based classification, and extensive dual-user memory, it delivers a professional monitoring experience that fits in your pocket, perfect for home use, travel, and active lifestyles.
1. At a mere 114 grams and with dimensions of 9.0×6.4×3.0 cm, the DBP-81E4 sets a high standard for portability. Its compact form factor makes it easy to slip into a bag, briefcase, or even a large pocket, ensuring you can maintain consistent blood pressure monitoring anywhere, anytime—whether at home, in the office, or on the road.
2. The monitor incorporates advanced sensor chips to achieve high measurement accuracy within ±3 mmHg. Crucially, it features a real-time motion detection indicator that alerts you if arm movement is detected during measurement. This guidance helps ensure proper posture, directly improving the reliability and consistency of every reading.
3. Following each measurement, the device provides immediate context using a visual classification indicator based on WHO guidelines. A color-coded light on the display instantly shows whether your reading falls within the Normal, Elevated, or Hypertension range, making results easy to interpret at a glance.
4. The large, high-contrast screen clearly presents your blood pressure and heart rate data. For added accessibility, an optional talking function is available, which audibly announces the measurement results. This feature is particularly beneficial for users with visual impairments or those who prefer auditory feedback.

Q1: How accurate is a wrist monitor compared to an upper arm monitor?
A1: The DBP-81E4 is designed with advanced chips and algorithms to deliver high accuracy (±3 mmHg). The key to reliable wrist measurement is correct posture: keeping your wrist at heart level during the reading. The built-in motion detection indicator is vital here, as it guides you to stay still and in position, which helps achieve accuracy comparable to many upper-arm models when used correctly.
Q2: Is the talking function standard, or is it an extra cost?
A2: The talking function is an optional feature. This allows for product configuration flexibility. You can choose the standard silent model or select the version with voice guidance pre-installed to better serve specific customer segments, such as the elderly or visually impaired users.
Q3: Is this monitor suitable for frequent travelers?
A3: Absolutely. Its lightweight (114g), compact size, and durable design make it an ideal travel companion. Unlike bulkier upper-arm monitors, it takes up minimal space. You can conveniently track your blood pressure while on business trips, vacations, or anytime you're away from home, helping you maintain your health routine without interruption.
