Lasair® III Airborne Particle Counter for Aerosol Particle Counters

The Lasair® III Aerosol Particle Counter from Particle Measuring Systems is designed with a sensitivity range of 0.3 - 25.0 µm. The Counter is mainly intended for cleanrooms with the users’ unique needs in mind. It sets the benchmark for portable aerosol particle counters in highly regulated environments; ensuring that the working environment is clean. It complies with the requirements of ISO 14644-1:2015 and ISO 21501-4.

The Lasair® III Aerosol Particle Counter can be used for both mobile and remote routine cleanroom monitoring. Particle Measuring Systems understand the requirements and have made the calculations required by users; cleanroom certification results can be procured through a local print-out, downloadable via USB in a secure format, or via the use of external software packages, such as FacilityNet, DataAnalyst, or FacilityNet Pharma Software.

On-board, hot-swappable batteries provide power for the unit. Power can also be provided via the use of an external AC power source, which can power the unit and charge the on-board batteries at the same time.

The Lasair® III Particle Counter accepts inputs from a broad range of environmental sensors through the four integrated 4-20 mA inputs. Wireless network communications are simplified with an externally-mounted wireless adapter, thus making communications with network systems a lot easier.
