SOLAIR 3350 5350

SOLAIRs incorporate our Extreme Life Laser Diode Technology sensor to produce the industry’s longest laser diode life of 20+ years MTTF (based on continuous 24/7 operation). The SOLAIR 3350 is the industry’s only 100 LPM 0.3 micron portable designed for continuous use.

SOLAIRs use the industry’s best UI (User Interface) to configure and operate the instrument. The intuitive ICON-driven screens and menus are easy to learn and use, which simplifies SOP writing, and support multiple languages.

SOLAIRs can store up to 3,000 records of particle count data from up to 8 particle channels and the configurable recipe database can store up to 50 recipes for sampling and reports. All data can be quickly and reliably transferred to a computer, a Facility Monitoring System or Building Automation System.

Secure data transfer (per 21 CFR Part 11) to a USB Flash Drive can be accomplished by using the Lighthouse Secure Data transfer feature and LMS Express or Express RT software. Flexible communication with these instruments is made possible by the integrated Ethernet, RS-485, USB and USB Flash Drive interfaces.

SOLAIRs are designed, manufactured and calibrated to ISO 21501-4 to ensure particle counting accuracy.
