GRIMM SMPS+E Scanning Mobility Particle Sizer with Faraday Cup Electrometer

Brand: Durag
Request Information

GRIMM has developed the SMPS+E system as a counter and sizer for nanoparticles in the size range of 0.8 nm to 1,094 nm in a wide range of concentrations (100 to 10⁸ particles/cm³). 

GRIMM's unique design of the FCE avoids internal contamination virtually completely by using rinsing air around the isolation of the Faraday Cup.
Features
