Hydrometer Case / Three-Place / Spring-Loaded / Flip-Top Closure
Three Place Flip-Top Hydrometer case is designed to conveniently carry three 15-inch API thermohydrometers. The black case features a rugged plastic outer shell with separate interior compartments, each lined with felt. The felt-lined lid is cut at a 30º angel to allow it to arc from the hydrometers when opening and closing, preventing stem breakage. Two models are available. The Spring-Loaded Closure, Model #403B088, uses a spring-loaded hinge to hold the lid in the open or closed position.
