FH950 Portable Velocity Meter

The perfect handheld solution for wastewater and environmental flow monitoring. The lightweight, battery-powered FH950 Velocity Flow Meter 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.

Knowledge gained through years of in-the-field flow measurement experience has come together in the Hach FH950 Handheld Flow Velocity Meter. Designed for use in both environmental and sewer/wastewater flow measurement scenarios — whether you’re profiling water current in streams and rivers, providing redundant verification of wastewater flow data, or selecting an optimal site for metering — even the smallest hassles have been addressed. From the field to the office, the Hach FH950 Handheld Flow Meter increases your efficiency at every turn.
