GRIMM SMPS+E Scanning Mobility Particle Sizer with Faraday Cup Electrometer
Brand: DuragGRIMM 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- Counts & sizes particles from 0.8 to 1,094 nm
- Sampling with up to 16 Hz
- Very low noise level
- Rinse air flow for fastest response time
- Three different DMAs available for maximum flexibility
- Compact and rugged
- Operates without any consumables
- Fully automated use with our software
- Three Analog inputs
- Self-test upon start-up assures highest reliability
