Definable electronic scale for field of retrieving

The utility model discloses a definable electronic scale for the field of retrieving. The definable electronic scale comprises a weighing sensor, an amplification filtering circuit, an AD switching circuit, a CPU (central processing unit), a display screen, an operation module, a voltage-stabilized source circuit and a communication module. The keyboard design of the common retrieving electronic scale in current retail market adopts the manner of a great quantity of keys, and different keys are set for operators to select, but since keys are too much, the use is inconvenient, and the application requirement of a retrieving system cannot be met. The definable electronic scale provided by the utility model is practically used by being matched with systems such as a centre platform or a city platform of the retrieving system, an operation interface is simplified, the use is more convenient, and the purposes of retrieving on specially supervised varieties and statistic on the varieties of key samples are achieved
