Merchant scales are scales that are used in stores to accurately measure the mass of products that customers buy. These can be foodstuffs, vegetables, fruits, meat, fish, but also other things such as textiles, cables, metals, and others.

Merchant scales must be precise and reliable, and in some countries they must be certified and calibrated regularly to ensure their accuracy and reliability. These scales are often connected to computer systems for sales records and tax calculation.

It is important to maintain and service merchant scales regularly to ensure their accuracy and reliability, and it is also important to protect them from vibrations, shocks and other influences that can affect their accuracy.
