Product Description

TVC have been manufacturing the ColcheK system, under exclusive licence for several years but felt it needed further development for a new generation.

After several months of development work, TVC are proud to launch the all new ColcheK2 unit. The new system has a digital display, depth measurement and threshold facility (which were not available on the previous system) and has had a complete overhaul of the internal electronics. The ColcheK2 now has a one button facility which eliminates errors in the initial set up, allowing far greater accuracy than was previously available. Based on the eddy current technique, the new unit is lighter, faster to set up and use and gives instant pass / fail indications with the easy to read and colour changing display.

The ColcheK2 system is a compact and rugged unit which utilises a remote field, through transmission Eddy Current technique. Through transmission probes are similar to differential probes – in basic terms, it’s two coils into two packages – and is therefore, unaffected by temperature and lift off. Through transmission probes detect corrosion and wall thinning remote from the drive coil allowing the below-ground inspection of planted steel lighting columns, without excavation around the column base.

Featuring a unique ultrasonic range finding system used to accurately feedback the search head depth inside the column, the ColcheK2 allows the operator to locate and identify the depth of an actual defect and its significance when related to depth. A defect located deep down is less significant than those located near to ground level. The cable entry on a column can also easily be identified by its depth and size and eliminated from the inspection.

Street lamps fail for a number of reasons, for example, bad installation, impacts or corrosion. Lighting columns are most susceptible to corrosion at and slightly below ground level; water, road salt and other chlorides and oxygen from the air combine to make this a highly corrosive area.

The ColcheK2 is currently used by inspection companies and local councils to inspect lighting columns prior to the installation of lights and decorations to check the column is suitable to bear the additional strain. ColcheK2 has been used on seaside resort lighting columns where summer decoration and additional lighting is common. It is also used in special event areas including those around the Isle of Man TT course prior to racing.
