The Lasair® III Aerosol Particle Counter is designed for cleanroom work 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 routine remote and mobile cleanroom monitoring. We know the requirments 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 the on-board, 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 on-board batteries. The Lasair III 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. The unit can be remotely managed via the built-in Web browser function or through ethernet to FacilityNet Pharma, FacilityNet, or FacilityPro and DataAnalyst Software.
