This is a low-power data recorder powered by batteries. This makes it suitable for unmanned long-term measurement in places where power is not available, such as remote areas, mountainous regions, and areas with heavy snowfall. It can be connected to strain gage civil engineering sensors (transducers) and civil engineering sensors (transducers) equipped with a temperature measuring function, and it can measure one channel. It also has operation and display sections, allowing for operations related to setting of measuring conditions and performing measurements. Channels: 1/unit
