Why no open competition
Single Suppliers Technical Reasons
Published justification

There are only two companies that can provide this type of equipment in the world, and we have used this company before and had very good interactions and support, we are already using the software that our people are familiar with, which means that we don't have to purchase another software package/licences or spend time re training our people. The market has been reviewed and the Ametek Detective X has been identified as the optimal detector for this work
