The Scanning Mobility Particle Sizer (SMPS™) is a special tool for studying really tiny particles in the air. It can tell us about the size of these particles accurately. The SMPS™ uses electricity and counts individual particles to give us information about their size in different categories. It's so detailed that it can measure up to 384 different size categories, with a super fine resolution of 128 categories per range.

The SMPS™ 3938 is flexible, meaning users can adjust it based on what they're studying. You can choose from four different tools to analyze particle movement, six tools to count particles, and two ways to neutralize particles. This allows measurements of particles ranging from 1 nanometer to 1 micrometer in size.

Applications:

1. Atmospheric studies and environmental monitoring.

2. Indoor air quality measurements.

3. Nucleation/condensation studies.

4. Combustion and engine exhaust studies.

5. Inhalation toxicology studies.

6. Nanotechnology research and materials synthesis.
