Overview
The VWR 34615-006 is a plain form hydrometer designed to measure the specific gravity (relative density) of liquids in the 1.200–1.420 range. This precision instrument is NIST-traceable and features a lead-free metal ballast for safe laboratory and industrial use. With a 300 mm length and clear graduations, it provides reliable, repeatable measurements in applications requiring high accuracy.
