Troubleshooting indoor air quality made easy
The particle counter is an essential tool in the facility maintenance, HVAC
and 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.
The new Fluke 985 Particle Counter is ideal for troubleshooting and
monitoring indoor air quality issues and verifying HVAC filter performance
and critical locations for ISO Class 5–9 certification.
With the ultra-light weight ergonomic design, easy to view color screen
with intuitive icons, on-screen trend graphs for easy and quick analysis,
the Fluke 985 is a must for any maintenance, HVAC and IAQ professional.
