Built on the heritage of Sondex™ technology, the Production Dual Caliper (PDC) assembly has a pair of caliper arm mechanisms set at 90° to each other for measuring the inside casing diameter in the X and Y axes. It is fully collapsible down to tool diameter for running into and pulling out of the hole.
The caliper is spring loaded and follows tubing ID while running in hole. It opens fully on leaving the tubing to enter the casing. Each arm operates as an independent unit exerting a constant radial force in any casing diameter.

- Identifying ID to correlate with changes in holdup patterns
- Simultaneous Operation with other PL Tools
- 1 3/16in UN 12tpi Sondex GO or other Heads
- Springbow version for open hole completions
- Combinable with other Ultrawire™ (UW) tools
