For 30 years, the TOPMES company has been engaged in its own development of data units for data collection. These units are used to collect data when measuring with municipal meters. These are mainly calipers, digital dial indicators and other meters that are commonly used in workplaces for quality control. Data from these units can be easily transferred to statistical software. Many years of experience with the development of units allow us to respond flexibly to customer needs and individually address their requirements.
