Applications

The Model 500 was designed for hydrological field measurement of surface water velocity in open channels, streams, and rivers. It pairs with Marsh-McBirney current meters to provide real-time flow data for water resources monitoring, hydraulic studies, and environmental assessments. Common in USGS operations and water management programs through the 1980s and beyond.

Condition: Used
This Marsh-McBirney Model 500 Universal Surface Readout has been inspected and is in good used condition. The aluminum rack-mount chassis shows typical age-related wear consistent with a unit manufactured in 1981 — light surface scuffing on the front panel and chassis exterior. The two analog panel meters (Angle and Magnitude) appear intact with no cracked or broken lenses visible in the photos. The rear connectors and multi-pin DIN connector show normal use wear. The interior circuit boards and components appear complete and undamaged based on the photos. Sold as inspected. Please view our photo set and contact us if you have any questions.
