The ordered execution has a 1.0 m probe lead and no standoff adapter. Preserve the installed penetration, fitting arrangement and matched transducer chain during replacement.
Important Notice: This is a 21000 housing with an included 8 mm probe, not an empty 24701 housing; confirm the complete marking before work.
These documents serve different purposes: the first records exact housing and probe-system data; the second covers installation checks, commissioning and acceptance.
