The RE-846U Rugged Data Acquisition System, built-in industrial-grade control computer and electronic hard disk, especially designed for data acquisition in various harsh environments such as on-vehicle, airborne, and shipboard, used to complete testing and long-term monitoring work in extreme environments such as strong vibration, high temperature, high humidity, etc.. RE-846U can be connected to a computer via a wired network (LAN) or wireless network (WiFi) to collect, transmit, store, display and analyze data in real time, and can also work stand-alone to gather and store data in real time. After connecting to the computer, the data can be exported for analysis and processing. RE-846U is suitable for many occasions such as infrastructure, civil engineering, mechanical engineering, railway transit, scientific research and so on.
