Scales are common measuring tools in daily life and are used in daily life and commodity trade. There are many types of scales, and each scale has different functions and ranges. Common scales include poles, bench scales, case scales, balances, and floor scales.

    The steelyard is a steelyard that was basically used before electronic scales became popular. It is light, classic, and extremely convenient to use. It is the main measurement tool for commodity circulation.

    Case scales, a small scale, are generally used on the counter, so they are called case scales and are divided into two categories: mechanical case scales and electronic pricing scales.

    The mechanical case scale is composed of a base, a bracket, a connecting rod, a tool rest, an adjustment weight, a load-bearing plate, a travel code, a scale piece, and an increasing weight. This scale is accurate, durable, and easy to use and maintain.

    The electronic pricing scale is composed of a high-precision resistance strain-type load cell, load-bearing device, and weighing display. It has the characteristics of high measurement accuracy, convenient and fast keyboard operation, and functions such as digital memory.

    According to the structural principle, platform scales can also be divided into two types: mechanical platform scales and electronic platform scales.

    The mechanical platform scale is composed of a load-bearing device, a reading device, a base lever, and a scale body. The advantage of the mechanical platform scale is that the structure is simple and the measurement is more accurate. As long as there is a flat and solid weighing frame or ground, it can be placed and used. The electronic platform scale is a small electronic weighing instrument using the principle of non-electrical measurement. It is composed of a load-bearing table, scale body, load cell, weighing display, and regulated power supply. It has the characteristics of light weight, convenient movement, and multiple functions, the display, and the scale body are connected by cables, and can be placed as needed when using.
