The American Educational brass double-hooked weight can be chained to other hooked weights or set flat, and is designed for use with hanging balances, and for applications including pressure, torque, and tensile strength testing. Brass weights are economical and durable.Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments. Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. Certified weights are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. Hooked and slotted weights are often used to measure pressure, torque, and tensile strength, and to demonstrate basic laws of physics. Calibration weights differ from lab weights, which are general purpose weights used to hold an object in place, similar to a paperweight. Science education products incorporate applied math and science principles into classroom projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.American Educational Products manufactures educational and supplemental learning materials including math, science, and reading/language arts for pre-kindergarten through grade 12 students. The company, founded in 1986, is headquartered in Fort Collins, CO.

The Rice Lake metric, stainless steel, leaf-style precision test weight meets American Society for Testing and Materials (ASTM) Class 2 specifications and has a turned-up end to enable lifting, a density of 7.95, and is designed for calibration or for use with microbalances. The weight is constructed of stainless steel for stability, resistance to corrosion, and low magnetic susceptibility. The kit includes a precision test weight, a handling glove, and a protective case. The weight meets ASTM E617, Class 2 specification for use as a reference standard for calibrating high-precision top-loading balances with a readability as low as 0.01g to 0.001g.Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments.

The Rice Lake U.S. customary (also referred to as English and avoirdupois), cast iron, slotted and interlocking test weight is designed for use with balances with weight hangers (not included). Painted cast iron weight has a chip-resistant paint that is corrosion-resistant and conforms to NIST Handbook 105-1 standards. A sealable adjusting cavity allows the weight to be fractionally adjusted to meet individual specifications. The weight meets American Society for Testing and Materials (ASTM) E617, Class 7 specification for rough weighing operations in physical and chemical laboratories, and for force-measuring apparatus.Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments.

The Ohaus metric, stainless steel precision calibration weight meets American Society for Testing and Materials (ASTM) Class 4 specifications, and is designed for use as a reference standard for calibrating other weights, or electronic balances and scales. The weight is constructed of stainless steel for stability, resistance to corrosion, and low magnetic susceptibility. A tapered neck enables the weight to be lifted with tweezers, reducing the risk of contaminants adhering to the weight. The weight meets ASTM E617, Class 4 specification for use as a reference standard for calibrating semi-analytic balances, and for student use. An optional National Voluntary Laboratory Accreditation Program (NVLAP) certificate ensures precision and traceability. The National Voluntary Laboratory Accreditation Program (NVLAP) accredits laboratories for compliance with ISO/IEC 17025 on the basis of their ability to meet the technical requirements set forth in NIST Handbook 150-2, and can provide accreditation to ANSI/NCSL Z540-1-1994. NVLAP calibrations and certifications meet all ISO, FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1 and Nuclear requirements and are traceable to NIST. Procedures and processes used to generate this multi-page certificate, as well as its format and content, are prescribed by NVLAP. The document contains customer name & address, date of calibration, equipment and standards used in the calibration, accuracy class, true mass value (mass in a vacuum), “As Found†mass correction (for recalibration), “As Left†mass correction, uncertainty of measurement process (uncertainty to tolerance ratios are guaranteed), environmental conditions during test, construction and density of the weight, calibration procedure, and a statement of traceability to NIST. Mutual recognition arrangements include The International Laboratory Accreditation Cooperation (ILAC), The Asia Pacific Laboratory Accreditation Cooperation (APLAC) and The National Cooperation for Laboratory Accreditation (NACLA).
