American Educational Brass Hooked Weight Set with Hanger, Metric

Model: 7-2500-12   |    Mpn: 7-2500-12   |    Ean: 0795721140264   |    PartNumber: 7-2500-12   |   Asin: B00657P2XM

The American Educational brass hooked weight with hanger is designed for use with hanging balances, and for applications that include pressure, torque, and tensile strength testing. Brass weights are economical and durable. The set of 12 weights includes 20g (9), 10g, and 5g (2) weights, a 50g weight hanger, and a plastic storage box.

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.

Rice Lake Cast Iron ASTM Class 7 Painted Grip Handle Test Weight, 5lbs Mass

 PartNumber: 12823   |   Asin: B006MWGHP2

The Rice Lake painted cast iron, grip handle test weight is available in metric and U.S. customary (also referred to as English and avoirdupois) and is designed for testing field standards and industrial devices. Painted cast iron weight has a chip-resistant paint that is corrosion-resistant and conforms to NIST Handbook 105-1 standards. 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. 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.

Rice Lake Weighing Systems manufactures weight-related and process-control equipment for use in research, scientific, and quality control labs. The company, which was founded in 1946 and is headquartered in Rice Lake, WI, meets International Organization for Standardization (ISO) 9001:2008 standards, and is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) to ISO/IEC 17025:2005.

  • Metric and U.S. customary grip handle weight for testing field standards and industrial devices
