Unique CF669 8-Electrode Body Composition Scale

The Unique CF669 is an eight-electrode body composition smart scale that measures 57 different body metrics — far beyond simple body weight. Stand on the platform, hold the integrated handles, and the scale uses bioelectrical impedance analysis (BIA) through both your feet and hands to calculate your body fat percentage, muscle mass, visceral fat, body water, bone mass, and dozens of other indicators. The wider 8-electrode reading is significantly more accurate than the 4-electrode foot-only design used in most consumer scales.

Key Features

• 57 body composition metrics — body weight, body fat %, muscle mass, BMI, visceral fat, body water, protein, bone mass, BMR, body age, fat-free body weight, and many more.
• 8-electrode bioelectrical impedance — readings through both feet and both hands for higher accuracy than foot-only scales.
• ≥98% body fat correlation vs INBODY 270 — the clinical reference unit used in many Australian gyms and clinics.
• WiFi and Bluetooth connectivity — pair to the Unique Health app via Bluetooth (≤10 m unobstructed) or WiFi (≤60 m unobstructed) for automatic data sync.
• 3.86-inch LED screen — clear readable display.
• 180 kg / 400 lb capacity, 0.05 kg / 0.1 lb division.
• 50-member family management — recognises and tracks multiple household members automatically.
• Baby Hold Mode — accurately weighs an infant by subtracting the parent's weight automatically.
• 500 mAh lithium battery, 90 days battery life per charge.
• 5 mm tempered glass platform with ITO coating for durability.

Who it's for

Households tracking weight management goals, fitness enthusiasts measuring training progress beyond simple weight, anyone managing diabetes or cardiovascular health where body composition trends matter more than weight alone, and families wanting one scale that automatically tracks each member's progress separately. The 8-electrode design and high INBODY-270 correlation make this a serious step up from typical consumer scales — closer to gym-grade accuracy at home.

Frequently Asked Questions

How accurate is bioelectrical impedance analysis (BIA)?
BIA is widely used in clinical body composition testing. The CF669's 8-electrode design (feet + hands) is significantly more accurate than 4-electrode (feet-only) consumer scales. The manufacturer reports ≥98% correlation with INBODY 270, the clinical reference. For best accuracy, weigh yourself at the same time of day with empty stomach and bladder.

Will it work without WiFi?
Yes — Bluetooth-only mode pairs the scale to your phone within 10 m. WiFi is optional but useful if you want readings to sync without your phone present (e.g., when other family members weigh themselves).

Is the data shared with anyone?
Data syncs to the Unique Health app on your phone or device. Review the app's privacy policy for details on how your data is handled. The scale itself doesn't transmit data without your account being signed in.

Can I use it during pregnancy?
Body composition readings during pregnancy can be unreliable due to fluid changes. The basic weight measurement remains accurate. Consult your GP or midwife before relying on body composition data while pregnant.
