The Opacimeter is a device used for measuring diesel exhausted gases opacity.

Supplied inside a steel cabinet with wheels for easy moving. It is equipped with computer, color printer, monitor and measuring chamber..
Adjustable filtering to fit regulations.
Real time opacity index N(%) and light absorption coefficient k(m-1) on screen representation.
Opacity curve on screen representation.
Full color results summary, yout can easily difference between vehicles that fit pollution regulations and vehicles that do not fit pollution regulations.
Engine revolutions and oil temperature real time visualisation if the TUR II module is attached.
Test results are displayed on the screen, printed or stored in a database.
Data from previous tests can be reloaded.
