Lankelma introduces UV video cone

Lankelma has enhanced its video cone to enable faster detection of fuel and oil ground contamination during land investigations.

Lankelma introduces UV video cone

The new cone features UV-emitting LEDs that can detect cold light emission luminescence from fuels and oils, providing a more accurate picture of the ground in real-time.

Lankelma reporting engineer Christopher Player explained: "Many industrial oils and fuels visibly emit fluorescence under ultra-violet conditions.

"The UV video cone can detect these emissions at low concentrations, with images streamed live to a monitor in the cone penetration testing (CPT) truck. Results can be used to enable real-time ground characterisation and to help target additional sampling and testing."

Pushed into the ground at 0.5cm/s using CPT equipment, the video cone has a camera and LEDs sitting behind a glass window. Alongside fuel and oil contamination, the cone allows particles such as shells and sand grains to be distinguished easily; small voids and gas bubbles are also visible.
