NALGENE® Hydrometers

Fast, Accurate Specific Gravity Measurements

Choose from salt or specific gravity (liquids heavier than water) scales. Salt version is excellent for food, beverage and other testing. Temperature standard is 60°F.
Specifications: Virtually unbreakable polycarbonate has glass-like clarity, and the same accuracy as glass. Not autoclavable. Polymethylpentene Hydrometer Jar (sold separately) has superior chemical resistance and a broad base for stability. Upper temperature limit of 135°C (243°F).
Compliance: Hydrometers are calibrated against NIST standards.
