Since the middle of June 2016, the UTP-Kalix 155 has been used to continuously improve incoming and outgoing goods inspections.
The UTP Kalix is characterized, in particular, by a very quick and accurate dimensional inspection, by larger sample quantities or complicated parts. The inspection tasks include o-rings and moulded parts made of elastomer, plastic and metal, including the possibility to determine many statistical values.
