Tanita RD-545 Ironman Bluetooth Compatible, Multi-Frequency, Segmental, Body Composition Monitor

The RD-545IM provides an in-depth analysis of 26 body composition readings. Measurements include: weight, body fat, muscle mass, muscle quality score, physique rating, bone mass, visceral fat, basal metabolic rate, metabolic age, total body water, and BMI. The addition of the hand electrodes allows the RD-545IM to perform a segmental fat and muscle analysis of the arms, legs, and trunk. Analyzing the balance of muscle mass and muscle quality between the arms and legs is essential for athletes competing in speed sports such as biking and swimming.

A newly developed pulse measurement function provides a resting Heart Rate Measurement value that can be tracked along with body composition, linking cardiovascular health to body composition values and fitness. Integrated Bluetooth 4.0 Technology automatically uploads all this data to the FREE Tanita HealthyEdge Mobile App (iPhone 4S or above, or Android phone 4.4 or above, found on iTunes or Google Play). Viewing results and tracking progress is simple with easy-to-read charts, graphs and assessments.

The RD-545IM is an FDA cleared 510(k) type 2 medical device, with a weighing capacity of 440 lb (200 kg). It uses BIA technology, which sends a safe, low-level electrical signal from foot and hand electrodes through the body to provide both a full body as well as segmental analysis. BIA is quick and non-invasive, and is one of the most thoroughly tested and reliable ways to measure body composition, clinically comparable to DXA (dual-energy x-ray absorptiometry) and hydrostatic (underwater) weighing.

Tanita is the World’s First Company to use dual frequency BIA in consumer scales. This advanced technology provides an additional level of accuracy to the body composition analysis process by providing essential data of a person’s intracellular and extracellular status. This allows us to analyze cellular structure, and determine the ‘quality’ of the muscle tissue, in addition to its mass. Both ‘quantity’ and ‘quality’ of muscles are important for achieving high levels of performance in many sporting events.

The RD-545IM also comes equipped with Athlete Mode. The Athlete Mode was developed to provide a more accurate reading for athletic body types. Athletes tend to be physiologically different then standard adult body types, due to muscle mass and hydration level difference. These differences would skew the body fat reading as high, when taken in the standard adult mode. 

An athlete is someone who:

  • Engages in intense physical activity for approximately 12 hours per week, or more
  • Belongs to a sports team or a sport organization that competes 
  • Is a professional athlete
  • Is looking to increase muscle mass
