Featuring an innovative eight-electrode design, it overcomes the technical limitations of traditional four-electrode body composition scales and delivers more accurate body composition analysis.

Product Specifications

Product Highlights
Segmented Dual-Frequency Eight-Electrode Measurement for More Accurate Body Fat Analysis
Unlike traditional four-electrode body composition scales, which estimate full-body data based primarily on measurements from the lower body, the S800 uses eight electrodes integrated into the handle and scale surface to apply multi-frequency bioelectrical signals to the body. It comprehensively measures five major body areas, including the upper limbs, torso, and lower limbs.

The S800 uses both high- and low-frequency alternating electrical signals. These signals can penetrate cell membranes, allowing the scale to accurately measure impedance values of intracellular and extracellular fluids and calculate body composition and health data. Compared with the medical-grade DEXA gold standard, the measurement results show a correlation of >0.97.

40 Body Metrics in One Measurement
Connect the scale to the app and step onto it to obtain 40 detailed body metrics, including body fat percentage, muscle mass, skeletal muscle mass, bone mass, basal metabolic rate (BMR), visceral fat level, body water percentage, BMI, heart rate, and more.

The system automatically generates a personalized body composition analysis report and provides professional health management recommendations.

One Scale for the Whole Family
The S800 supports storing health data for up to 36 family members, with each member’s data recorded independently. It also features a dedicated body fat measurement mode for teenagers, helping parents track and quantify changes in their children’s physical development.

The scale also supports data synchronization between the Mi Home/Xiaomi Home app and the Xiaomi Sports Health app.

On-Scale Interaction Prompts for More Accurate Measurements
The LED display on the scale features new hand and foot positioning detection. When an abnormal posture is detected, an orange indicator lights up to remind users to adjust their grip or standing posture, helping ensure more accurate measurements.

Larger and Wider Handle Electrodes
The handle features enlarged and widened electrode plates, making it suitable for different hand sizes with fewer grip restrictions. The handle cable comes with an automatic retractable reel that retracts the cable when loosened and magnetically attaches the handle to the edge of the scale.

ITO-Coated Tempered Glass Surface — Stylish and Practical
The scale features a large 320 × 345 mm tempered glass surface, providing ample room even for users wearing EU size 48 footwear. The ITO coating creates a smooth, flat surface that is easy to clean.

The scale body features rounded edges to reduce the risk of injuries caused by sharp corners, combining safety with an elegant appearance.

Long Battery Life, Hassle-Free Use
Powered by four AA batteries, the S800 can provide more than 180 days of battery life under laboratory conditions of 25°C with three weigh-ins per day.
