Description

The RD-545 InnerScan PRO is one of, the world’s first and only consumer product line offering multi-frequency, Bluetooth wireless, segmental body composition measurement. Taking fitness and health monitoring to the highest standard. More measurements, greater accuracy, over a wider range of body types. Where resolution, repeatability and precision are taken higher as only multi-frequency technology can offer. The RD-545 InnerScan PRO 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-545 InnerScan PRO to perform a segmental fat and muscle analysis of the arms, legs, and trunk (5 segmental fat measurements, 5 segmental muscle mass measurements). 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 Healthy Edge 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 Tanita RD-545 InnerScan PRO uses the very latest technology to provide the most accurate body analysis possible, while also sending this data to your smart phone, or tablet, for detailed review and analysis. Tanita is the World’s First Company to use multi-frequency Bioelectrical Impedance Analysis (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 an analyzed measurement on a cellular structure, and determines the ‘quality’ of the muscle tissue, in addition to its muscle mass. Both ‘quantity’ and ‘quality’ of muscles are important for achieving high levels of performance in many sporting events. Analysis of the cellular data from the BIA measurements allows the RD-545 InnerScan PRO to determine the quality of the muscle tissue, in addition to mass. Knowing muscle quality and muscle mass is essential for training analysis and monitoring injuries. The RD-545 PRO has 4 electrodes on the platform as well as 4 on the display handle for a total of eight electrodes. The eight electrodes allow the RD-545 PRO to provide a segmental review of the body, this allows an analysis of muscle mass and body fat percentage in each arm, each leg, and the trunk area. Make sure all fingers make contact with the electrodes, don't pull the cable beyond the red mark, and keep your legs and arms extend for accurate readings. Launched in 1923, we are the leader in manufacturing Japanese-Made scales: Professional, Body, Consumer, Kitchen & Mini Scales TANITA offers products that give you the ability to monitor your body, the effects of diet and your fitness routine.

    • Two thumbs up, 5 star product!
Review Image by Paul Hamilton
I know this scale is expensive, but truly worth the price tag if you would like full and accurate insight of your body composition. My wife and I feel it’s worth the money and we’re both enjoying every feature of the scale and app. I don’t write reviews often, but felt it was necessary because the only review for this product is a one star review, which almost deterred me from making the purchase. I’m glad I did more research and selected the Tanita RD-545pro. We had the Qardio Base prior to purchasing this one which was very inconsistent and a frustrating scale. It doesn’t even come close to competing with the Tanita scale. ... show more

    • Easily the most disappointing tech I have ever owned
Dare to compare" is Tanita’s marketing claim, so I did—and the results are far from impressive. On paper, the specs are solid, with advanced features like muscle quality scoring and segmental body composition analysis. However, that's where the praise stops. The build quality is cheap plastic, and it looks and feels uninspired for a premium product. Unlike every other consumer scale I’ve encountered, this one lacks a proper LCD display on the scale itself to show basic metrics like weight. Instead, there’s an antiquated, tiny LCD screen on the handheld grip. The grip connects to the scale with a flimsy cable that feels like it will either break or get stuck in no time. The scale is painfully unintuitive to use. Stepping on it doesn’t automatically begin a measurement like you’d expect. Instead, you need to hit the power button on the grip and then lift it to start—a redundant and clunky process. The scale also doesn’t auto-detect the grip position, further emphasizing how dated the technology feels. Setup was an even bigger nightmare. You first download the app, register on the my.tanita website, update your profile, and then attempt measurements. Even after jumping through these hoops, measurements often fail, time out, or get stuck. Worse yet, there are no clear prompts or guidance on what went wrong or how to fix it. While the LCD on the grip is outdated, the app is truly the worst part. It feels antiquated, clunky, and entirely unpolished. For a scale at this price point, this level of app integration is unacceptable. If you’re buying this solely for its unique measurement claims, it might suffice, but as an overall product, it’s an absolute disaster. I regret the time I wasted trying to make this work. The user experience is abysmal, and the presentation doesn’t live up to even basic expectations. This scale is a huge letdown. ... show more

    • Great scale, when used with the EU version of the My Tanita app.
In the US use Aptoid to sideload the EU version of the My Tanita app. Syncs flawlessly with the scale over bluetooth and is much more user friendly, better graphics and user interface. Lightyears ahead of the Healthy Edge app available in the US. Thank me later.

    • Multiple usage on APP is an headache
Everything is good, report is fine but multiple person usage on APP is not good and not easy to pass from myself to my wife is really headache and bluetooth transfer is not possible in some actions.

    • 2026 and still no good app or connections to apps
This is my 2nd tanita scale. My first was in 2008 and was wonderful but then I bought a Garmin index for importing and better history logging. The Garmin was crap for accuracy so... Back to tanita. I bought this because I expected by now they would finally have a good upload and history method. Sadly disappointed. The app is meh. And nothing connects to tanita healthy edge. I should have saved $200 and bought the $196 version and manually entered my data on a spreadsheet. ... show more

    • App is junk
Love the scale itself but I am not sure how to rate it free of the app necessary for it use. The app is one of the worst I have ever used and my wife is about ready to toss the whole thing out due to connection issues. In my case the app sometimes will not show all the data, just weight. I have to shut down the app and restart to get it to show all the data. My wife's phone says it is connected to the scale but says there is no data available despite just weighing herself and the scale indicating she is the user being weighed. Not sure what to do about that one yet but we are still in the beginning phase trying to make it all work. There is simply too much data to just use it free of the app and if all one wants is weight there are much cheaper scales that are just as good. Our old scale used wifi and our app connected to the internet to get data. Really wish this scale did that so we did not have to try to sink directly with the scale and deal with these connection nightmares. The Apple App store has a 2 out of 5 rating on the app. I think that high. Note: For the last year or so I have been trying to get the app to connect to my phone every once in a while. Despite following advice of Tanita I have only used the on-scale metrics. The app won't connect. Absolute waste of money, the app is simply puzzling in its current form although I must admit I can't really use it but I am not even sure how I would update the scale readings. It certainly does not present an easy way to transfer scale readings to the phone. I certainly will never get a Tanita scale again. So far the scale seems accurate from one use to another. As far as its accuracy I am not entirely sure but honestly don't care for the most part. My weight shows pretty close to my previous scale. I am more interested in trends. If my actual weight or body fat is a few points off I don't care for the most part as long as I can count on the trends. That said, this scale has users put in where they live so the scale can compensate for different gravities in different places on earth. I do like the athletic mode to the scale. I am pretty muscular and work out a lot. Caliper tests show me to be about 8% less body fat than most impedance scales. This one is pretty close to calipers. My guess is the greater accuracy is not just due to the athletic mode. The hand unit adds to the accuracy. The way impedance works just using hands or feet will not likely lead to very accurate results and show trends that only apply to part of the body. For me the data is too rich. I really don't care much, nor understand, all the data presented on different parts of the body. Not sure I care that my right arm is measured to be 1% body fat and are "under". Have not even figured out what that means yet. My guess is it means I should have more fat on my arms. Wish I could transfer some visceral fat. Not sure how impedance tells of muscle quality. Guessing it does not really. I'm happy my metabolic age is 30 years younger than I am but again Im pretty sure impedance can tell us little about metabolic age. There are some good lab tests for that. Of course it is easy to just ignore the data that is not useful to you. All in all I recommend the scale. Perhaps in time we will get it all figured out and the app won't be such a nightmare. If my research is correct the competition is not very good at this price point and with these features. Pricey but if the features are important to you there does not seem to be much competition. ... show more
