Pi is a battery powered handheld inspection tool that has been developed to assist in the inspection of pipelines within the energy and processing industries.

With 4 passive TeraHertz receivers sampling at a rate of 50 kHz, Pi enables real time, non contact inspection.

Pi has been developed to assist in the inspection of pipelines with no metallic vapour barrier or metal cladding. Pi enables rapid inspection of pipelines fitted with low thermally conductive insulation materials and protected using non-metallic cladding, such as GRP or polyurethane .
