Cold-Chain Rugged Mobile Computer is a specialized industrial handheld terminal optimized for low-temperature cold storage and refrigerated logistics environments, powered by the Android system with customized anti-freezing hardware design. Unlike regular rugged handheld devices, it adopts low-temperature resistant batteries, anti-condensation screens and special internal components that run steadily under minus 20°C or even lower temperatures without shutdown or screen failure. It maintains standard IP67 dustproof and waterproof rugged structure, capable of withstanding drops, water splashes and frost accumulation in cold warehouses, refrigerated trucks and frozen food transfer stations. Equipped with built-in barcode scanning engines and optional RFID modules, it records batch information, temperature logs and cargo codes for fresh produce, seafood and pharmaceutical products. Wi-Fi, 4G and Bluetooth enable real-time cold chain data upload, while large local storage supports offline data recording in signal-lacking cold storage areas. This terminal tracks the whole cold chain circulation to monitor cargo integrity. It is widely used in frozen food warehousing, pharmaceutical cold drug transportation, fresh market sorting and cold storage inventory checking, eliminating equipment freeze failure risks and ensuring complete traceability of low-temperature goods.
