It has recently come to our attention that unofficial /counterfeit equipments including tunnel sensors and CEMS products have been found in the China market bearing the CODEL name  or are branded as Mandrake-Codel or Codel Technology and such spurious products are also being distributed to other parts of the world.  We believe they have been produced and placed by Mandrake Environmental Technologies Ltd, using their own components from unverified sources.
