Which Weighing Scale is the Best Analogue or Digital?

The two types of weighing scales in the market are analogue and digital weighing scales. Analog is a traditional model of weighing scale while digital is the modern version of weighing scale. Both analogue and digital weighing scales have their own sets of advantages and disadvantages. The best option for you depends upon your individual requirements which can only be determined after knowing about the working and pros and cons of both kinds of weighing scales.

Working:

Analogue scales use a spring mechanism. Springs are present under the surface of the machine which contract whenever weight is put on the surface. The contracting springs rotate a spinning wheel which has weight markings on it. A pointer rests over any particular weight marking when the wheel stops spinning.

The digital scale uses digital sensors to measure weight. The load cells present in a digital scale has strain gauges which activate the sensors whenever they are strained due to the application of weight. A converter digitises the weight signal, which is displayed in the form of electronic digits on the LCD screen.

Points of Comparison 

Accuracy: Digital scales use smart digital sensors which makes them more accurate as compared to analogue scales which use springs. In case of an analogue scale, you need to take some effort to see the exact weight reading on which the pointer rests. But a digital scale displays the exact weight in figures on the screen. However, even on a digital scale, there can be a percentage of error which is more in the case of cheaper models.

Ease of Use: Analog scales do not need to be turned on. You need to stand on the scale whenever you need to check your weight. There is also a need for a battery on an analogue scale. Digital scales run on batteries. There may be times when you need to check on your weight urgently, but the battery dies down, and you don’t have a spare battery. Digital scales need to be turned on and off. However, there are models which switch on and off automatically.

Durability: Analog scales use spring mechanism which tends to wear out with time. This leads to errors in readings. Moisture can also adversely affect the spring mechanism. Digital scales, on the other hand, use digital sensors which do not get damaged easily. Warranties of 1 year and more are provided on digital scales.

Calibration: Analog scales need calibration. All you need to do is twist the dial to calibrate the analogue scale. Digital scales requiring manual calibration need some efforts because the precise method as per the instructions manual must be followed. However, digital scales equipped with the auto-calibration feature are also available in the market.

Extra features: Analog scales do not have extra features other than the main task of measuring weight. Digital scales, on the other hand, can display extra information such as BMR, fat%, water%, etc. Many models can also store the data and even connect to mobile apps.

Price: Analog scales are priced more than digital scales. Digital scales with more features are even more expensive.
