GRIMM miniCAST 7882 Soot Generator

The real soot generator miniCAST 7882 is small, portable and can be used for stationary and mobile applications.

The CAST is the best known soot generator for standard soot particles. The CAST supplies soot particles which are generated in a well defined flame, that simulates the combustion processes in combustion engines. The operation principle is based on solid know-how and practical experiences from many years of leading aerosol research and development activities. The miniCAST Model 7882 is aiming to supply soot particles for applications requiring lower particle output or lower particle concentration.

Its design and features meet the requirements of different applications in laboratories and for mobile needs. The miniCAST model 7882 generates a small particle flow with a constant particle concentration (mass and particle number) and allows testing particle monitoring devices. The internal dilution air reduces the particle concentration, this allows measuring particles without external dilution and saving expense respectively. The diluted particle flow can be directly led in to particle monitoring devices such as SMPS.
