Sizing and counting particles by the TSI OPS model 3330

Optical Particle Sizer model 3330 (OPS) is a light, portable unit that provides fast and accurate measurement of particle concentration and particle size distribution using single particle counting technology. Backed by over 40 years of aerosol instrumentation design experience, the OPS uses state-of-the-art optics with 120° light collection and sophisticated electronics processing resulting in precision, high quality data. Rigorous factory calibration standards ensure measurement accuracy. The model 3330 particle sizers can be used alone, or it can be placed in TSI’s weatherproof Environmental Enclosure.

Features and benefits:

  • Size resolution < 5% at 0.5 μm
  • Size range: 0.3 – 10 μm in up to 16 channels
  • Wide concentration range from 0 to 3000 particles/cm3
  • User adjustable size channels
  • Fully compliant with ISO 21501-04
  • Filter-based sample collection for later gravimetric or chemical analysis
  • Battery-powered for up to 12 hours of operation
  • Built-in data logging capability for up to 30,000 samples

Quality optical instruments are useful in a variety of applications due to their ease of use, fast measurement time, robustness, and reliability. A few common applications are listed below.

  • Filter testing (i.e. ASHRAE 52.2)
