The J1667 packages include a meter that sits at the end of the stack of a heavy-duty vehicle and is designed to meet US and Canadian SAE J1667 specifications. The MOT packages include a partial flow smoke meter that is designed to meet European specifications for testing light duty vehicles. Each model comes with the latest Windows diagnostic software that enables vehicles to be quickly tested and diagnosed. Each model is available as a portable unit connected to a laptop computer or as a complete stand-alone meter with computer workstation. These models are approved in many countries around the world and provide advanced software for diagnosing emissions related problems.

The software allows units to be displayed in Density (m -1 ), K, or Percent opacity at different path lengths. Both full and partial flow units are available. The paragraphs below show the advantages of Heavy Duty Diagnostic Center™.

Light Duty MOT

The light duty MOT diesel smoke meter is designed to meet the opacity measurement requirements of PTB in Germany, M.O.T in the UK, ISO 3173 and is approved in many countries around the world.
