Caused by increasing accuracy and robustness of digital scales classic, the importance of analog scales more and more subsides. Also the fact that cheap digital scales are barely more expensive than mechanically alternatives is responsible for the low availability of these kinds of classic scales.

Analog scales – Pros

The most important advantage of an analog scale: you are not in need of any power supply. No batteries, no accumulator, no plug. Beside that, pan scales are more durable that any others. Digital and spring scales can be easily destroyed by overloading, which is not possible with pan scales.

Analog scales – Cons

In short terms: Analog scales are not as accurate as digital ones.

Kinds of analogous scales

There are two basic variants of mechanically scales: classical spring scales known from your physic class and grandmas good old pan scales (no modern scale could ever help to get apple cakes like that one were made with a pan scale).



Hang it: Spring scale

Spring scales

Most of you are familar with spring scales from your physic classes and maybe you were used to label it „Newtonmeter“ (which is in fact a wrong term).
The principle is simple: the wheight is determined by the tension of the spring. Be carefull with overloading: this would disable the scale forever.



Known from grandmas kitchen and from court: Pan scale.

Pan scales

Perhaps the most classical scale of all. Pan scales are indispensable in any kitchen and widespreaded in households managed in a retro-style.
The principle is based on a fixed point in the middle of the weighing beam. When both scales were brought to equilibrium, the result can be concluded by the weight placed on each side. PS: dont use a scale blindfolded – you wont be able to assess properly .
