2 Channel Air Particle Sensors

The Airnet® II and IIs 2 Channel Air Particle Sensors meet the specifications of ISO 21501-4 to measure the size and number of particles suspended in the air for real-time monitoring of defect-causing particles.

A simple and cost-effective way to monitor your cleanroom, the Airnet II Air Particle Sensor provides unparalleled performance with data transmission capabilities for remote monitoring.

Versatile power options combined with an ultra-small footprint makes the Airnet II Air Particle Sensor easy to install right where you need it. The unit can be configured to accept distributed power from an in-house system, local power plugin (Polycarbonate version only), or power over ethernet (PoE).

Data integrity is maintained through the use of a data queue feature that continues to gather data even if communication is lost due to a power outage. To ensure proper flow conditions and vacuum system operation, these units incorporate a Dynamic Flow Sensing system that will alarm with a 15% change in flow conditions.

For situations where sampling is required during the vaporized hydrogen peroxide (VHP) sterilization process, an optional VHP-compatible unit is available for a simple installation without complex valving. Download the Airnet® 510 XR Resilince to Vaporized Hydrogen Peroxide app note.
