H-B DURAC B61823-0400 Safety 39/51 Degree API Combined Form Thermo-Hydrometer

These hydrometers, with a convenient, built-in, mercury-free thermometer, come in a wide range of models measuring the relative density (specific gravity) of oil and petroleum related products in various ranges from -1 degrees to 101 degreesAPI in accordance with American Petroleum Institute (API) standards. Made of lead free ballast and glass, these combined form thermo-hydrometers are 381mm (15") long and contain an enclosed thermometer with a temperature scale of 0/150 degrees F and blue spirit organic liquid fill. They are individually serialized and conform to the accuracy requirements for ASTM thermo-hydrometers. Temperature standardization is 60 degrees F (15 degrees C). DURAC Safety Combined Form Thermo-Hydrometers are 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 with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: Combined form thermo-hydrometers should be stored in a clean, dry, safe place, and should not be subjected to extreme temperatures. Built-in thermometers should be used as a general reference only. For temperature critical applications, a calibrated standard thermometer is recommended.
