The ALPHA TG25 Auto Tide Gauge is a high-precision, low-power device for measuring water pressure/depth. It offers flexible sampling intervals, large storage (2 million data points), and durable sensors. The included CWMlanager software enables easy configuration, data export, and analysis. With ultra-low power consumption (years of operation on one battery) and an accurate internal clock, it is widely used in marine, environmental, hydrological, and meteorological applications.
