Real-time particulate matter detection


Dekati® eFilter™ is completely new instrument that adds real-time PM detection into a standard gravimetric filter holder. Dekati® eFilter™ assembly is in one compact single unit with automated operation. Fits directly into all existing exhaust PM filter sampling systems including CVS tunnels. Real-time signal changes the standard filter holder into a sensitive, dynamic measurement instrument for modern routine emission measurements. Separate pump is used in the real-time detection module to make sure the gravimetric filter sampling is not affected by the real-time measurement.
