Product Description
Determine API gravity of crude oil and petroleum products with hydrometers matched to ASTM designations. Each range carries its ASTM H number for easy selection against your test method. They are serialized for traceability. Accurate density readings support consistent product quality and reliable records.
This listing is for Kimble catalog number 52130-1931: Plain Form API ASTM Hydrometer, API 19°-31°, ASTM 3H. They are calibrated to ASTM specification and graduated in 0.1 degree API steps. Each hydrometer is soda-lime glass with a lead-free ballast of steel pellets in a binder. A serial number is printed on the scale, and a certificate of traceability confirms manufacture with devices calibrated to NIST-traceable standards. Ranges run from API -1 to +11 (ASTM 1H) up to API 89 to 101 (ASTM 10H). LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
Key Features
