Air quality checks that fit your budget

If speed, portability, and low cost describe your priorities in a particle counter, consider the Met One Model 228/229. Spot checks require little time to complete.

Choose either the 228 to take a six second sample displayed in particles per liter or cubic foot, or the 229 to display the number of particles in 0.1 cubic feet of air after a one minute sample. Maximize your time and results by taking multiple readings.

Better assess indoor air quality and check indoor air filter systems for pathogensized particles. Quickly determine the quality of HEPA filter performance. Take the 228/229 most anywhere; at only 0.65 kg (1.5 pounds) it conveniently transports and can be used at multiple locations in the field. A rugged exterior withstands frequent use in many types of environments. Combined with an 8-hour rechargeable battery, the 228/229 meets the needs of simple, portable particle counting.

Operating the 228/229 is just as easy. Check particle counts with a single press of a button. The one-button interface and the large digital display make it ideal for the layman. Lightweight, rugged and easy to use, Met One 228/229 Portable Airborne Particle Counters are the simple cost-effective solution that will fit a variety of uses and budgets.
