The Troemner stainless steel double-hooked weight set can be chained to other hooked weights, and is designed for use with hanging balances, and for applications including pressure, torque, and tensile strength testing (set of 9). The weight is constructed of stainless steel for stability, resistance to corrosion, and low magnetic susceptibility. The set of nine weights includes two each of the 200g and 20g weights, one each of the 1,000g, 500g, 100g, 50g, and 10g weights, and an impact-resistant polypropylene case.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.Troemner manufactures precision weights and laboratory equipment for laboratory, industrial, retail, and medical applications. The company, which was founded in 1838 and is headquartered in Thorofare, NJ, meets ISO 9001:2008 standards, and is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP), United Kingdom Accreditation Service (UKAS), and ISO/IEC 17025.
