Hach FH950 Portable Velocity Meter

Pine Item #51817

The lightweight, battery-powered FH950 Velocity Flow Meter, with a 20' cable, was designed to provide accurate velocity measurements while simplifying the entire measurement process in rugged field environments.  Multiple user-friendly features designed into the FH950 allow you to quickly and easily determine stream velocities for required discharge measurements, or use the FH950 to quickly calibrate area velocity flow meters, or verify primary devices such as weirs and flumes.

Reduce person-hours by 50%
The step-by-step user interface simplifies programming, delivers real-time data, and downloads directly to the PC, allowing a single person to take the readings and eliminating post-site visit manual data transfer from the logbook to the PC.
