Due to their robust construction the POMA series delivers a reliable and stable performance even under harsh conditions, such as in industrial manufacturing environments. These kinds of environments, where temperature fluctuations and floor vibrations are present, generally create a special range of challenges for measuring machines. However, these challenges are easily overcome by the POMA series. The basic granite construction of the POMA projectors has a low thermal expansion and is not sensitive to floor vibrations or other external influences.
