Introduction of a Revolutionary Direct Push Device CP-1000 XRF Cone Penetrometer

The EDXRF Underground CP-1000…The World’s Only Tube Based Spectrometer Capable of Being Pushed Into… Soils Sediments Sludge And Many More…

Statement of Opportunity Cone Penetrometer Sub-surface characterization of soils and minerals is a necessary step in planning field activities. It is costly and often environmentally unfriendly. Inexpensive field solutions are desired to reduce costs. Miscalculation Excavation & Sampling (example: Super-Fund Site Clean Up) Additional Cost = Equipment Usage & Remobilization Creates Hazard Disturbs Site Wait On Lab Results Others Extended CEMS Usage Site Expansion Workers Comp/ Exposure Liability
