GE Panametrics 25DL-RR is a dedicated corrosion survey variant of the 25DL platform. RR stands for Reduction Rate. Operators input the nominal original wall thickness; the instrument automatically computes residual thickness and thinning percentage after corrosion or erosion, which simplifies corrosion assessment and compliance recording.

It supports single-sided ultrasonic measurement for carbon steel, stainless steel, alloy and other metallic components. Compatible with series contact transducers including 580P2-M2JR, UTXDR 4MHz dual-element probes, matched with signal cables such as 259205-PR, 336766 PR and 100100 ultrasonic couplant.

Built-in data logger stores thousands of measurement records with location tags; measurement data can be uploaded to PC for inspection report archiving. Configurable min/max thickness capture, upper/lower thickness alarm, inch/metric unit switching and multiple ultrasonic measurement modes. Powered by rechargeable battery for long-duration field survey.

Differentiate from other 25DL variants:

This model has been discontinued for new production; mainly used for equipment maintenance and spare replacement on existing inspection fleets. Typical applications cover power plants, chemical factories, refineries, shipyards, pipeline periodic corrosion thickness scanning.

Customers can purchase standalone 25DL-RR main unit, or complete inspection kits composed of ultrasonic transducer, signal cable, coupling gel and protective carrying case.
