The new Hach FH950 measures both velocity and depth. It simplifies setup with its menu-driven user interface. Real-time velocity is graphed on the large color display, which offers a quick visual reading of velocity trends. The color bar indicator on the display guides the user to position the sensor at the ideal depth location, making discharge measurement collection efficient and trouble-free. The Hach FH950 auto-calculates discharge volumes based on USGS and ISO methods. Measurements are easily downloaded to a computer via USB connection, allowing for single-person data collection and eliminating the need for manual data transfer from logbook to PC.
