H-B Instrument B61891-3100 Lead Free Ballast/Glass Soil Analysis ASTM 151H Hydrometer, Traceable to NIST, Range: 0.995/1.038L, 11″ Length
These hydrometers are used to determine the specific gravity of soil in the range of 0.995 to 1.038, or -5 to 60 g/L (using a weight by volume scale). Made of lead free ballast and glass, these 280mm (11”) long hydrometers conform to the accuracy requirements of ASTM hydrometers. Each is individually serialized and has a temperature standardization of 68 degrees F/68 degrees F. DURAC Soil Analysis ASTM 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: Soil analysis hydrometers should be stored in a clean, dry, safe place, and should not be subjected to extreme temperatures.

Backed with a PLR 100% Satisfaction Guarantee.
PLR filters continue the brand’s long legacy of superior optical solutions. All our filters are carefully formulated to ensure consistent color and accuracy throughout the entire surface of the glass. Why? Consistent color means consistent high quality results. We know that a poorly made filter makes a great lens and camera worthless, that’s why the our frame rings are constructed of special alloys that won’t expand or contract over time or due to temperature extremes-it’s also why we back our filters with an 10 year warranty-because we engineer them to last.
Like all PLR optics, PLR filters are precision manufactured to the most demanding of tolerances. This ensures consistent high quality results even after years of use.
