Product – Comparison

Because the OCA, DCAT and SVT series of measuring devices have some overlapping application focus the following comparison tool is designed to help you decide which of them is the right choice for your needs. For a more detailed explanation of the differences and similarities and which device is best suited to tackle your questions, please feel free to contact us. Our sales team is eager to help you!

In the table below, two product series of the DataPhysics Instruments range of measuring systems can be selected and compared side by side. For the availability of features the following symbols are used:
