Reliable scales: how to make your choice?
When you want to closely monitor the evolution of your weight, the scale remains one of the best tools. But there is balance and balance, because the accessory has evolved enormously over the years. Here is a review of the different types of scale, as well as some tips for choosing a truly reliable device.
The different types of scales
The first (and most important) criterion to take into account when choosing a reliable scale is undoubtedly its type.
The mechanical scale
This is the basic model, where the weight display is done on a dial with a needle. On the strength side, there is nothing to complain about: this type of scale is often made of metal, does not require batteries and resists the wear of time. On the reliability side, the balance is less enthusiastic: the graduation per kilogram does not allow to know its weight to the nearest gram. In addition, accuracy can deteriorate over the years; If you notice that the needle does not return to 0 after weighing, despite a prior adjustment (thanks to the tare wheel), then the tool is out of order. In view of these characteristics, it is easy to conclude that the mechanical scale is not the most reliable, but that it is a good alternative for people without major weight problems, who want to control their weight load from time to time.
The electronic scale
Whether analog or digital, this type of scale is significantly more reliable. Indeed, the display is done on an LCD screen, for better readability and shares a weight measured to 100 grams, for increased accuracy. On the other hand, like any electronic device, this type of scale needs maintenance:
- batteries should be changed regularly;
- The scale will undoubtedly be calibrated as soon as you buy, but regular use can deregulate it. Also it will be necessary to calibrate it from time to time (refer to the instructions for use);
- The environment can affect the reliability of weighing – proximity to electronic devices, ambient temperature, non-flat surface.
Moreover, the electronic scale remains a relatively reliable device. Moreover, some models can record the different , for a more precise follow-up of its weight curve.
The impedance meter
In recent years, scales have become more and more sophisticated and can not only give an indication of the total body mass of an individual, but also data relating to body compositiontag. Theimpedance lot of information on health: weight, ,body fat mass, body fat rate,visceral fatspleen , muscle mass, bone mass, water mass,Basal metabolismor metabolic age. Bioimpedance thus offers fairly reliable information on the constituents of weight (body mass being a figure that is sometimes arbitrary). And for those who are worried about the technological aspect – this type of bathroom scale that relies on sending a very low intensity current through the body, via the sensors on the plate – it is safe for health. The only limitation: this type of scale, which compares the individual’s information with previously recorded statistical data (based on age, size, sex and level ofPhysical Activity), can display sometimes approximate results. Reliability is therefore, again, quite relative.
The connected scale
Finally, the last type of scale, very fashionable at the moment: the Connected Scaletag. It is an “intelligent” impedance meter, synchronized with another device such as a smartphone, a bracelet or a connected watch. Thus, the data is immediately sent to the device and can be viewed on a screen, rather than on the scale. In general, they are recorded on the associatedMobile Application, for more practicality in weight monitoring. Like the impedance meter, this type of scale is rather reliable, except:
- the compatibility of the scale and the operating system of the smartphone or connected watch;
- the terms of use – sometimes the application does not allow to associate different user accounts with the scale.
What other criteria for choosing a reliable bathroom scale?
You will have understood: the most modern models are undoubtedly the most reliable, because they are based on advanced technology. In addition, they make it possible to estimate the various parameters associated with weight, by providing health information.
Other reliability criteria can be taken into account when choosing your balance:
- the price, although it is no longer necessarily a guarantee of quality. Indeed, some scales display an amazing price-quality ratio;
- the precision range;
- the quality of the software, in the case of an impedance meter;
- the manufacturer’s know-how.
Finally, remember that weighing conditions are just as important as the scale. A reliable weighing should always be done in the morning, on an empty stomach, naked or in underwear, after a visit to the toilet, at a fixed day and time, on a perfectly flat surface.
