Each thermo-hydrometer comes with a Certificate of Conformance traceable to NIST. Bio-degradable, non-mercury performance liquid provides safe and easy cleanup in case of breakage. Scales are bold and easy to read. All instruments measure 15" in length and come with a built-in thermometer (range shown in listing). Hydrometer cylinder of at least 390 mm x 50 mm is required (See Thomas No. 6024Y50).
