H-B DURAC B61898-1000 ASTM 84H Precision, Individually Calibrated 0.750/0.800 Specific Gravity Hydrometer

Available in a variety of individually calibrated models measuring specific gravity of petroleum products and heavy liquids in various ranges from 0.650 to 1.500, with 0.0005 divisions in accordance with the American Society of Testing Materials (ASTM) E100 standards. Specific gravity hydrometers are the most widely used hydrometer in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Made of lead free ballast and glass, these 330mm (13”) long plain form hydrometers are calibrated traceable to NIST standards at three specific gravity points and are supplied with a detailed calibration report stating corrections to one-tenth of the smallest division. They are individually serialized and conform to the accuracy requirements of ASTM hydrometers. Temperature standardization is 60 degrees F/60 degrees F. These ASTM Hydrometers are calibrated and hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC/MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged in a recyclable deluxe storage box. Made in the USA. Note: ASTM calibrated hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.
