The TOFD Caliper is a simple, pocket-sized scanner for TOFD inspection of welds of any material. It holds a single pair of transducers, an encoder and enables the separation to be quickly adjusted using a single thumb screw.
Overview

This pocket-sized, manually-operated scanner allows for quick and easy TOFD inspection of welds of any material. The TOFD Caliper is ideal for inspecting small or difficult to access areas and can be used for welds of any orientation on 3” pipes up to flat plate.

A compact, lightweight, user friendly single axis scanner, the TOFD Caliper is the perfect tool to provide a quick and simple, manual weld inspection. It is very easy to setup with the probe separation being adjusted from a single thumb screw.

The TOFD Caliper operates in any orientation on surfaces from 3” pipe up to flat plate, suitable for inspecting welds on pipework, pressure vessels, storage tanks and structural components.

The TOFD Caliper holds a single pair of transducers with the wedges very easily clipped into the arms. Interchanging a wedge takes seconds. It is compatible with the full range of wedges and TOFD transducers. Wedges can be plastic, brass, or stainless steel and are available at 45°, 60° and 70° as standard.

The TOFD Caliper can operate with any encoded TOFD instrument. It includes a wheel encoder wired to suit the customer’s instrumentation. The TOFD Caliper is often used as the most suitable training tool for TOFD inspectors due to its simplicity, reliability and quick wedge interchange.
