Dekati® eFilter™

“Dekati® eFilter™ is a novel instrument that adds real-time PM detection into a standard gravimetric filter holder. The Dekati® eFilter™ assembly is approximately the same size as a normal PM filter holder and it fits directly into existing vehicle exhaust PM filter sampling systems. In addition to the standard gravimetric filter measurement, the Dekati® eFilter™ gives a real-time signal throughout the filter sampling period which allows monitoring PM accumulation on the filter during different stages of the filter sampling. This real-time signal can be used e.g. to control and verify the quality of the gravimetric PM measurement, to detect high emitting particle sources and to verify stable particle concentration in the sample during filter sampling.
