The hazardous waste explosion-proof electronic scale integrates Internet of Things technology, weighing sensors, data communication and centralized management software, forming a complete system covering from the weighing point to the management center. The electronic scale automatically collects weight data and is equipped with radio frequency identification readers, cameras, hazardous waste weighing terminals and other peripheral devices. When goods are weighed, the system can automatically identify the identity of the goods, capture images of the goods and the goods themselves, and immediately digitize the precise weight data.

The mixed electronic scale includes an electronic scale, an air valve, a screw feeder, a buffer hopper, a mixing machine and a buffer bin. At the lower outlet of the electronic scale, there is an air valve, and through the corresponding screw feeder, a conveying path is formed to connect with the corresponding buffer hopper. The outlets of the two buffer hoppers correspond to the feed inlet of the mixing machine, and the lower end of the mixing machine is a buffer bin. According to the formula, several different materials are automatically weighed and mixed as required, and the given values of each material are corrected by the initial "advance quantity".
