The Orum CONT.AIR Handheld Air Particle Counter for Cleanroom Monitoring accurately measure particles in the air to ensure cleanroom compliance and effective contamination control in regulated and controlled environments.

Portable Particle Counting for Cleanroom Classification and Environmental Monitoring

The Orum CONT.AIR is a handheld particle counter designed to detect, count and size particles in the air in real time.
It supports cleanroom classification, routine monitoring and environmental control in pharmaceutical, industrial and research environments.
Unlike microbial air samplers, the CONT.AIR measures non-viable particles, which can act as carriers of contamination.

Key Benefits
