The difference between a good radiograph and a great one often lies in the quality of the accessories used during setup. This category includes the essential precision tools required to calibrate your shots, mark your location, and ensure image clarity. Here, you will find Image Quality Indicators (IQIs)—also known as penetrameters—used to prove the sensitivity of your inspection, as well as Lead Letters and Numbers for permanent identification of welds and dates. From Film Cassettes and Lead Screens that reduce scatter radiation to Magnet Holders and Centering Spiders, these tools are designed to help technicians achieve perfect alignment and compliance with the most demanding NDT codes.
