How to choose scales for pregnant women?
Bathroom scales which are divided into two types – electronic and mechanical are intended for measurement of weight in house conditions. Generally pregnant women will suit any scales, but the electronic device is more preferable mechanical as it has much less error in measurement, at scales with mechanical type of work the error can make about 1 kg, besides, the division price often corresponds to 1 kg.

The most part of the scales presented on sale is calculated at most on 160 kg, but it is desirable to check restrictions in advance – some compact and economical models are calculated on smaller weight, for example, up to 100 kg. If you have an excess body weight, consider it upon purchase – during pregnancy the woman can gain several dozen kg. Norm increase in weight up to 16 kg by the time of childbirth is considered. Pay attention to models with functions of the computer analysis of weight if in them there are programs for pregnant women. Such devices can keep data, make the schedule of an increase in weight and compare it to norms.
