What is in the Air You are Breathing?

A particle counter or dust monitor can offer a portable solution for determining airborne particle concentrations, and is an essential tool in facility maintenance, HVAC and any IAQ professional’s toolbox. From filter testing to indoor air quality investigations, the particle counter equips the user with valuable data concerning the concentration and source of particulates in the tested environment. Use of such equipment can provide an immediate response to occupant complaints or can be used as part of a comprehensive preventative maintenance program.

The demand for accurate and reliable indoor air quality instrumentation continues to grow as we spend more time indoors than ever before. However, Indoor air quality issues can be complex due to the diversity of indoor environments. Assessment of the air quality in your indoor environment should begin with quality, professional-grade monitors. Met One has a diverse offering of instruments to do the job, such as the Aerocet-531S, Aerocet-831, the 804, and the GT-324. Particle counts and mass concentration readings together are critical to determining the overall quality of air in indoor settings. We offer a handheld device capable of calculating both in our Aerocet 531S.
