Necessary in environments that regularly use weighing devices, calibration weights guarantee that measuring standards are met. These calibration weight sets provide effective testing of weighing instruments and guarantee that results remain accurate. Calibration weight kits are available in various weights - 1g, 2g, 5g, 10, 20g and so on - and tolerances to maintain any analytical balance or laboratory scale resolution and sensitivity.
