Mettler Toledo CarePac with Carrying Case, OIML

Mettler Toledo CarePac with International Organization of Legal Metrology (OIML) weights includes a calibration certificate and is designed for calibrating high-precision weights and balances. The weight is constructed of polished stainless steel for stability, resistance to corrosion, and low magnetic susceptibility, and a polished surface highlights wear that can affect weight precision. The set includes two test weights, tweezers, cleanroom-approved gloves and cleaning cloth, a storage case, and a calibration certificate to ensure traceability. The weights in the CarePac meet OIML R111, Class E2, F1, or F2 specifications for calibration precision. OIML Class E2 weights are used as a reference standard for calibrating other weights and high-precision analytical balances with a readability as low as 0.1mg to 0.01mg. OIML Class F1 weights are used to calibrate high precision top-loading balances with readability as low as 0.01g to 0.001g. OIML Class F2 weights are used to calibrate semi-analytical balances, and for student use.

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.

Mettler-Toledo manufactures precision instruments for use in research, scientific, and quality control labs for the pharmaceutical, chemical, food, and cosmetics industries. This company, founded in 1989, is headquartered in Switzerland.
