Analog Bathroom Scale

Analog bathroom scales are the oldest type of bathroom scales. Analog bathroom scales are also known as mechanical or dial scales. These scales display weight by using pointer method. When you stand on the scale the pointer on the dial moves to your corresponding weight position. Analog scales are available in various shapes and sizes.

Analog bathroom scales are of two types: spring based and weight based. Weight based scales are mainly used by medical professionals. They are known to deliver most consistent and accurate readings at all times. Spring base scales are mainly used in homes. They are difficult to adjust. These scales work on a principle of spring and levers. On the inside of a scale there are four levers, dial with a rack and pinion. When a person stands on the scale the levers moves causes the spring to move up and down. The springs up and down motion is then converted into side motion by pivots. This motion is then transmitted to rack and pinion arrangement, which converts it into a circular motion to turn the dial. Therefore, in analog scales it the position in which you stand in is very important as the spring displacement depends on this.

Analog scales have also matured over the years. They now boast a more attractive and accurate dial. The dials are large so that reading them is easy. As analog bathroom scales use springs, regular use can wear out the spring and cause the scale to malfunction. Regular calibration is required for them to function properly. Analog scales do not require any batteries to run on.

Analog scale are best if you only want to use it for weight checking and no other requirements then analog scales are the best for you. Digital scales are slowly overtaking analog scales, as they are more accurate and have a long life. Analog scales lack in their ability to store previous readings.  Some major companies that manufacture analog scales are Taylor, Health o meter, Tanita, Seca, Salter.

If you are on a budget then analog scales are definitely the choice for you than digital scales. Analog scales are also easy to use and they do not require any power to work on. Analog scales are easy to repair and are virtually maintenance free at they do not regularly need batteries.
