The Lasair® III Cleanroom Particle Counter is designed with your unique needs in mind. It sets the standard for portable aerosol particle counters in highly regulated environments, so you can make sure your environment is clean.
It can be used for both remote and mobile routine cleanroom monitoring. We know the requirements and we’ve done the calculations for you; cleanroom certification results are available through a local printout, downloadable via USB
in a secure format, or through the use of external software packages, such as DataAnalyst, FacilityNet, or FacilityNet Pharma Software.
Power is provided to the unit through the use of onboard, hot-swappable batteries. Power can also be provided through the use of an external AC power source, which can simultaneously power the unit and charge the onboard batteries.
The Lasair III Cleanroom Particle Counter accepts inputs from a wide range of environmental sensors through the four built-in 4-20 mA inputs. Wireless network communications are made easy with an externally mounted wireless adapter, simplifying communications with network systems.
Find the best particle counter for your application by using Particle Measuring Systems’ (PMS) particle counter finder tool.

Catalog of spare parts, sensors and optional accessories for the Lasair III airborne particle counter.
Printer Paper is for use with standard printers, as well as for cleanroom-appropriate devices.
The Spare Lithium Battery is to keep on hand for replacement power as needed. Also available as a four-pack.
The High-Pressure Diffuser lets you count particles in high-pressure gas lines by taking gas at pressures between 40 and 100psi and reducing it to a level acceptable to particle counters designed for atmospheric pressure.
The Hand-Held Isokenetic Sampling Probe works in conjunction with a 1CFM LASAIR III Particle Counter isokinetic in 90FPM airflow.
DataAnalyst allows for downloading, archiving, and reporting for full compliance with all secure data transfer requirements.Reports can be generated to meet industry requirements and configured to include raw data, tabular data, and statistical and graphical formats.
