Thermal Imaging Rugged Handheld Terminal is a heavy-duty industrial handheld device integrating infrared thermal imaging camera, barcode scanning and mobile computing functions, built on Android system with high three-proof standards of IP65 or above. The reinforced shell can resist dust, splashing water and 1.5-meter free falls, stably operating in harsh sites like power plants, chemical factories and mechanical workshops with drastic temperature changes. Its core thermal module captures invisible heat distribution images, detecting abnormal overheating of circuits, pipelines and equipment components in real time. Meanwhile, it supports 1D/2D barcode identification and optional RFID reading to label target equipment and store temperature data. With built-in 4G, Wi-Fi and Bluetooth, thermal photos and inspection records can be uploaded to the management platform instantly, and ample local storage supports offline inspection tasks without network access. This multi-functional terminal combines temperature troubleshooting and asset data collection. It is widely applied in power equipment patrol, building pipeline inspection, factory mechanical maintenance and fire safety checking, helping staff locate hidden risks rapidly while completing digital equipment filing to boost inspection accuracy and safety management efficiency.
