More than a scale — a window into your body

With 25 tracked body metrics displayed on an upgraded 3.5″ TFT colour screen, you get richer, more actionable data the moment you step off — no need to reach for your phone first.

Precision you can rely on

Tired of scales that give you a number but not the full story? The S400 Pro uses dual-frequency bioelectrical impedance measurement to deliver more precise body composition readings, capturing metrics like body fat percentage, muscle mass, and more with greater accuracy than single-frequency alternatives. Pair it with the Mijia app to track your progress over time and view detailed reports that help you make sense of your health journey.

A design built for daily use

The S400 Pro isn’t just capable — it looks the part too. A seamless fusion of technology and aesthetics, it features a large 300 x 300 mm ITO-coated scale surface that provides a stable, comfortable platform for measurement, finished with a distinctive metallic Mijia logo. Its major design upgrade makes stepping on and reading results genuinely effortless.

Set it up and step on — for months

With up to 150 days of battery life, the S400 Pro is built to stay out of your way. There’s no need to worry about frequent battery changes disrupting your routine — simply step on and let the scale do the rest, day after day.
