- Abstract:
- Platform-type manual mass comparators are commonly used for the calibration of high precision heavy mass standards. While some automated heavy mass calibration systems are available commercially, they are very expensive and are not economically viable for most laboratories offering calibration services.
NMC, A*STAR has developed a low-cost, automatable, weights handling system for use with commercially available platform type mass comparators. This system is designed to be versatile and adaptable for easy loading and unloading of reference and test mass during calibrations.
With this system, it is possible to achieve a marked improvement in repeatability measurement by as much as three times as compared with manual weighing using the same comparator. The system reduces the wear and tear of the mass standards and drastically reduces the risk of injury to calibration personnel due to lifting of heavy masses. - Keywords:
